O FOREWORD

The Controlled Fusion Atomic Data Center (CFADC) was

founded informally at Oak Ridge National Laboratory by Clarence

F. Barnett in 1959, and was officially established six years

later. The continuing mission of the CFADC is to identify,

compile, evaluate and recommend data on atomic and molecular

collision processes which are important in fusion energy

research. "Barney" dedicated much of his professional career to

the promotion of effective scientific communication between the

atomic and fusion research communities, and was still-actively

engaged in this mission at the time of his death in 1989. This

"RedboOk" volume represents a major part of his continuing

professional efforts during the years following his formal

retirement from ORNL in 1985. Barnett's insights, guidance and

dedication to this mission will.be sorely missed by the CFADC

and by the fusion research community.

O Series PreZace

The primary objective of the Controlled Fusion Atomic Data

Center at Oak Ridge National Laboratory is to publish and

distribute handbooks containing numerical and graphical cross-

section and other physical data relevant to fusion energy

research. In 1977, a two-volume compilation was published as

ORNL reports ORNL-5206 and ORNL-5207. Since that time, a

large volume of pertinent data has become available, necessi-

tating an update and expansion of the previous compilation. .

The specific volumes in this series, entitled "Atomic Data forFusion," are listed below.

INTRODUCTION

This volume contains recommended cross-section and rate'coefficient data for inelastic collisions between hydrogen,

heliumand lithium atoms, molecules and ions, and encompasses

383 different reactions of primary interest in fusion research.

Published experimental and theoretical data have been collected

and evaluated, and the recommended data are presented in

tabular, graphical and parametrized form. Inelastic processesinclude excitation and spectral-line emission, charge exchange,

ionization, stripping, dissociation and particle interchange

reactions. Emphasis has been given to the range of collision

energies appropriate to diagnostic and modelling applications infusion-energy research.

The data which form the _ basis for this volume of

recommended d_ta are those which were available as of September

1988. The bibliographic files of the ORNL Controlled Fusion

Atomic Data Center provided the lists of references for thisvolume. In the vast majority of cases, the numerical data were

obtained from the original publications, either from tables

where available, or from figures using a precision graphical

digitizer system. The rms uncertainty associated with the

digitization system was determinedto be less than 2%.

The recommended data in this compilation are based almost

O exclusively on experimental data. Theoretical data have beenconsidered when it was desirable to extend the measurements to

higher or lower collision energies, and also for a few importantreactions where experimental data were unavailable. Specific

references to the literature and notes are presented for each

reaction, along with an estimated uncertainty in the recommendedcross section. The latter was determined from uncertainties

quoted in the original data sources, and also from theconsistency of the data when more than one source was available.To determinethe recommended cross sections in the latter case,

relative weightings were made on the basis of the reliability of

the different experimental methods used. In some cases,

possible effects on the measurements due to other competing

processes were also considered in detez_ining the reconunendedcross section and its estimated uncertainty. For some

reactions, it was not possible to estimate an uncertainty. In

all cases, the estimated accuracies of the recommended dataarebelieved to have been conservatively estimated, and are intended

to represent upper limits.

Reaction rate coefficients have been calculated from the

recommended cross-section data where appropriate for fusion

applications, and where the energy range of the available data

permits. These are based on Maxwellian velocity distributionsfor each reactant, where each may be characterized by a

O different temperature, and also for the case of a monoenergetic

I-2

(neutral) beam interacting with a Maxwellian distribution. Thetemperature ranges for the calculated rate coefficients are

constrained by the energy range over which cross-section dataare available. The tabulated Values for the rate coefficients

have been flagged in those temperature ranges where the limited

energy range of the data appreciably influences their accuracy.

For convenience, least-squares Chebyshev polynomial fits to

the recommended cross-sections and rate coefficients are pre-sented for each reaction. These polynomial fits are indicated

graphically, and a statement is made concerning the accuracy ofeach fit to the recommended data. Practical deuails on the

least-squares fits and sample computer programs for rapidlygenerating the recommended cross sections and rate coefficients

from the fitting coefficients are presented in Appendix i.

For further ease of retrieval and application of the recom-mended cross-section data, a PC-DOS formatted diskette has been

prepared and is available for distribution. Included on this

diskette are data files with the Chebyshev fitting coefficients

for each reaction encoded in ALADDIN format, 1,2 along with a copy

of the ALADDIN program (written in FORTRAN-77). The ALADDIN

program and data files may also be conveniently transmitted by

electronic mail. Further details about ALADDIN are presented in

Appendix 2, along with samples of the data entries from each

chapter. Information about how to obtain the program and data @files for this and other compilations may also be found inAppendix 2.

Ac___curacy: E > 20 eV/a,_u - 20%; E < 20 eV/ainu - factor 2 (see notes)

Notes: (i) Measurements made in the 1970's showed structure in the cross section curve in the

energy range of 40 - 700 eV/ainu. More recent measurements (Ref. 67 and 68) show no

evidence of structure and the cross sections are approximately a factor of 2 less than

those reported in Refs. 63-66 for energies less than 400 eV.

(2) Mosley (Ref. 63) found a sharp rise in the cross section for energies less than 30

eV/amu. Irt the region of overlap, with the most recent papers, Mosely was a factor of

two greater. Thus, the data of Mosely have been reduced by approximately a factor of

two which more nearly coincides with the theoretical data of Re[. 280.

(3) The data below i0 eV/ainu should be used with cautJ•on.

(4) Plotted is the II+ e1_ergy with II- at rest.

(5) The interaction energy is given by Eint=EH+/2.

(6) See Dolder's review (Ref. 69) for a d_scuss]on of this reaction.

For a Chebyshev fit of the above cross sections it is necessary tc, use the following parameters.

ot_p._: (i) At energies less than 1.5x103 eV/amu the cross sections were determined by measurlng fm&the slow ion current produced in the collisions. The cross section was calculated

assuming that H_+ ions formed in ionizing collisions were negligible. _tlmer et al.(Ref. 213) found the ratio of H+/_2 + produced to be .024 at 7.5xi eV/amu andincreased monotonically to .2 at 25x10J eV/amu.

(2) A proportional counter was used in many experiments at energies greater than ixl03eV/amu to measure H 2 formed in the collision.

(3) lt is well known that the II + electron c.... _ + apture cross sections are dependent on the

vIbratlonal levels of the Incident H 2 ion. see the following set of data for themagnitude of thl_ effect which increases as the energy decreases.

(5) Electron capture data for II2+ in He are very scarce. The data presented here shouldbe used with caution.

For Chebyshev fits of the above cross sections it Is necessary to use the following parameters.

_ccuracy: E < 2x103 eV/amu - unknown; E > 2x103 eV/amu - 20%

Notes= (i) The data between 40 - 2000 eV/amu have been interpolated

(2) The data of Moran and Conrads (Ref_ 107) are essentially independent of energy in

the 250 - 800 eV/amu region and are approximately a factor of I0 above the values shown.

(3) The low energy data ( E < 2x103 eV/amu) of Stedeford and Hasted(Ref. 82) are 1 to

2 orders of magnitude greater than the extrapolated data.

(4) The data below 2x103 eV/amu have large uncertainties

(5) In the experiments cited the He+ metastable state population is dependent on the ion

source used and the opera_tlng parameters of the source. As the metastable populationincreases the total cross section increases.

tor a Chebyshev fit of the above cross sections it is necessary to use the following parameters.

Eml n = 2.4E-03 eV/amu, Emsx = 7.0E+05 eV/amu

+(i the measurements a problem arises from the mutual repulsion between the He + andHe . The repulsion results in scattering with some of the ions not reaching thedetector which has a finite acceptance angle. These measurements are termed partialcross sections.

(2) The total cross section data____$_h from theoretical values in _ef. 28_ and 391. Thetheoretlcal data has been joined a smooth curve between 6x10 J and i0 eV/amu.(3) For this simple one electron, resonant system, the theoretical data should beaccurate to within 20%.

FOr Chebyshev fits of £he above cross sections it _s necessary to use the following parameters.

(Partial) Emi n = 7.lE+00 eV/amu, Ema x = 1.6E+04 eV/amu

(Total) Emi n 8.5E+00 eV/amu, Ema x 3.0E+05 eV/amu

(i) At energies less than 2 keV/amu the rest!its of Fite et al. (Ref. 5) and Nutt et

al. (Ref. 23) diverge by as much as a factor of iO. This is believed to be due to

the fact that the results reported by Fite et al. were obtained by measuring the slow ions

produced in the collision, and are less reliable than those of Nutt et al at low energies.

(2) No experimental data exist below 500 eV/amu. Cross sections below 500 eV/amu were

taken from calculations of Ref. 57 and 58 using multi-state close coupling methods.

Accurac___! E < 250 _V/amu - see notes; E > 250 eV/amu - 20%

Nots..___s! (1) The data for energies less than 250 eV/amu have been obtained using the theoretical

results of Cohen and Bardsley (Ref. 149). From 250 eV/amu the data have been

extrapolated down to 2.5 eV/amu to Join smoothly with the theoretical results.

(2) Johnson et al. (Ref. 265) have measured the rate coefficient to be 4.8xi0 -14 cm3/sat a temperature of 30D K.

(3) Theoretlcal values of the rate coefficient of Bardsley et al. (Ref. 266) are:

T:100 K, k-4.43x10 -14 cm3/s; 300 K, 4.24xi0 -14 cm3/s; 600 K, 4.02xi0 -14 om3/s; I000 K,3.79xi0 "14 cm3/s; 3000 Z, 3.25x10 "14 cm3/s.

For a Chebyshev fit of the above cross sections lt is necessary to use the following parameters.

Agcuracy_ Energy < 3x103 eV/amu - factor 21 3x103 eV/amu < E < ixl05 eV/amu - 30%1 E > ixl05eV/amu - 50%

(i) For energies greater than 5x103 eV/amu, the crossed beam results of references 12 A

and 14 are in good agreement with the data obtained using the tungsten oven H cell

employed in the other experimental references.

(2) No corrections were applied for cascading but the effect is believed to be no more

than 5% ....

(3) Data for energies greater than 1.2x105 eV/amu were taken from the theoretical paper

by Shakeshaft (refo 70) who computed the cross sections using time-dependent impact

parameter coupled-state equations.

(4) Cross sections in the energy range Ixl03 - 5x103 eV/amu rely on the experimental

results of Morgan et al (ref. 15) and theoretical result_ of ref. 71 and 72.

(5) Cross sections for the 2s state were found by mixing the 2s and 2p states with anelectric field.

For a Chebyshev fit of the above cross section it is necessary to use the following parameters.

Eml n = 2_0E+03 eV/amu, Emc x = 2.0E+05 eV/amu

Notes: (i) Thomas in ref. 20 has applied a correction to ref. 19.

(2) All cross sections have beer, normalized to either the H + + H 2 -> H(2p) + }12+ or e- +H(Is) -> e- + H(2p) cross sections.

(3) Cross sections for H impact energies greater than 3xi04 eV/amu rely on computations

of Shakeshaft (ref. 70). Data were obtained using time-dependent impact parameter

coupled-state equations.

(4) The cross section (dl) for capture into state i is determined by measuring the

emission cross section (_ij) for a transition from state i to j, correcting for any

branching from state i, and correcting for cascading from upper states.

(5) Cascading from upper states to the 2p state is less than 5%. Thus _ (2p) =

a(Lyman-u) emission cross section°4

Notess (i) The cross section _i for capture into state J is determined by measuring the

emission cross section (uiJ) for a transition from state i to J, correcting for any

branching from state i and correcting for cascading from upper states.

(2) The capture cross section into excited states is measured by making use of the'

Doppler shift. The total _ (L_) was determined from the total of the shifted and

unshifted radiation.

Accuracy: See notes

Notes_ (i) Large errors are usually associated with measuring optical emission from excited

states which arise from electron capture, dissooiative or excitation collisions. The

cross sections reported here are for electron capture collisions resulting in Balmer-a A

emission (n=3->2), _=6562.79 i) and Balmer-_ emission (n=4->2, k=4861.33 Al. Errors

arise mainly from the detecter calibration which for the visible spectrum varies over [

many orders of magnitude. We can only estimate the error to be more than a factor of 2

for H a .

(2) Tne H a emission cross section is found from the following relation - o(H a) = ,(3sl +

.I18,(3p) + _(3d).

(3) Cascading from upper levels contrlbu_e no more than 5% to the measured cro_s

sections.

(4) Ha cross sections below 3x103 eV/amu were found by normalizing Hess's results (ref.

137 and 138) to other results at 3x103 eV/amu.

(5) Very little data are available for Balmer-_ (H_) emission cross sections.

(6) H p cross sections below 3x103 eV/amu were found by normalizing Hess's data (refs.

137 and 138) at 3x103 eV/amu to Hughes et al data (ref. 139).

(7) No estimate is given for errors in the H_ data.

(8) Data are available for capture in the 4s state (see refs. 130 and 132).

Notesz (I) Large error s are usually associated with measuring optical emission from excited

states which arise either from electron capture, dissociative, or excitation collisions.

The cross sections reported here are for electron capture of the fast proton into a fast

H atom. Errors arise m alnly from absolute calibration of the detector which for the

visible spectrum varies over orders of magnitude from blue to red. We estimate the data ,_

presented to be accurate to a factor of 2.

(2) The cross section (a i ) for capture into state i is determined by measuring the

emission cross section (_lj) for a transition from state i to J, correcting for any

Notes: (i) H Balmer-a emission is H a with _=556.3 nm.

(2) Balmer-a emission is the n=3->2 transition and is equal to a(3s) + .118 _(3p) +

-(3d) where o(31) is the cross section for capture into each n=3 angular momentum state.

The factor .I18 is for the branching ratio of the 3p state, i

(3) If the cross sections from pages B-40, B-46 and B-52 are summed using this formula

then the H a cross sections are within 10-20% o_ the evaluated sums.

e(1) Very few papers report absolute cross sections. The overall assessmenL og tile data

is in doubt due to the validity of the different normalization schemes.

(2) Cascade from higher states iS usually neglected and can contribute up to a 5% error

in the reported cross sections,

(3) The cross section (oi) for capture into state i is determined by measuring the

elnissjon cross section (aii ) for a transition from state i to J, correcting for any

branching and correcting for cascading from upper states. Pcr Balmer-_ emission from

the n=3 state, the cross section a(ll_)=a(3s) + .188 _(3p) + a(3d).

For a Chebysbev fit of the above cross sections it is necessary to use the following parameters.

Accuracy: Unknown O

Notes: (i) Very few papers report absolute cross sections. The overall assessment of the data

is in doubt due to the validity of the different normalization schemes.

(2) Cascade from higher states is usually neglected but can contribute up to 5% error in

the reported cross section measurements.

(3i The cross section (oi) for capture into state i is determined by measuring the

emission cross section (aij) for a transition from state i to j, correcting for

cascading from upper states and correcting for any branching. For Balmer- a emission

from the n=3 state the cross section _(H_)=a(3s) + .l!8a(3p) + s(3d). _

Accuracy: Unknown

Notes: (i) Very few papers report the absolute cross sections. The overall assessment of the

data is in doubt due to the validity of the different normalization schemes.

(2) Cascade from higher states is usually neglected, but can contribute up to a 5% error

in the reported cross section.

(2) Cross sections between 9x103 and Ixl05 _v/amu were obtained by interpolation between

the low and high energy data. s

(3) For energies less than ixl05 ev/amu the cross sections measured by Hippler et al

Notes: (1) The 3s and 3d states could not be determined separately due to the degeneracy of

states In lie + . I_

(2) Capture into the ground state is negligible at low energies for a H target.

(3) The cross section (ai) for capture into state i is determined by measuring the

emission cross section (oij) for a transition from state i to j, correcting for any

branching from state _ and correcting for cascading from upper states.

For Chebyshev fits of the above cross sections it is necessary to use the following parameters,

(3p) Eml n = 1.6E+03 eV/amu, Ems x = 1.0E+04 eV/amu

(3s+3d) Eml n = 2.5E+03 eV/amu, Ema x = 1.0E+04 eV/amu

_,L_tes: (I) The Ba]mer-a cross sections are determined by measuring the emission_1" A = 656.28nm from the n = 3 states of H and are related to the levelexcitation cross sections as follows: c(Ha) = 0(3s) + 0.118 0(3p) + 0(3d). The I

factor 0.118 arises from the branching ratio for decay of the 3p state. (2) Theg

0(3s) have been corrected for cascading.

Notes: (I ) The 28 cross sect io11 has been measured by f ie].d.-.irtchlced_'oz_ of byma11-_ radjatlon (2s -> 2[) -> is). If cascade is rleglected,

this is equa.t to the cross section for H(2s) formation. (2) Tile 2p cross isection was determii_ed by measuring the blauan-c, emiss,/on. If cascade is

neglected, this is equal to the cross section for H(2P) formatiotl,

Notes: (i) The slow positive charge formation cross section is the sum of the

ionization cross section and the electron capture cross section, o_ = oi (H2 +

+ e) + o0-i (H" + Hz+). The dissociative ionization cross section (H + H2 -> H

+ H + + H + e) is only 2-5% of the HZ_ formation cross section in this energy

range. (2 ) At low energies most of the H2 + arises from electron capture

collisions. (3) The electron production cross section is the sum of ionizationand the electron loss or stripping cross section o = ol (H2 . + e) + o01 (H + + e).

Notes.- (I) The total cross section for producing slow He 2_ ions is the sum of the

double ionizatioll cross section (H + + He -> H_ + He 2_ + 2e) and the electron capture

cross section (H . + He -> H- + He2.). (2) At energies less than 3x.]O5_ eV/ainu the

production of He 2. is dominated by double electrozl capture collisions. (3) For

cross sections involving the formation of He + see the preceding set of data.

Notes: (i) The measurement of meta'stable helium iz] H 2 Js very difficult andthe results are inconsistent Therefore, the data should not be taken as

absolute. (2 ) The processes to form ions are : (a) Penning ionization (Pl )He(21S) + H 2 -> He + H2 _ + e; (b) Associative lorlization (AI) He(21S) + H 2 ->

Hell2_ + e; (c) Dissociative ionizatio!l (DI) He(21S) + H2 -> He + H' + H 4 e;

(d) Rearrangement ionization (RI) He(21S) + H2 -> Hell_ + H + e; (e) ]on pair

pro,!'._ction (IPP) He(21S) + H2 --> He + II_ + H-. The sum of tllese processes is

kllown as total ionization or chemionizat ion. (3 ) Note that the Pellilingionization and the total ionization are the s_ne within experimental errors;(4) The energy of the 21S state is 20.61 eV with a lifetime of 2xlO -2 soc.

Accuracy.' Ionization 60%

He 2_ Production - 30%

Notes: (1) The production of He 2_ arises fronl two processes: (a) Charge exchange (H

. He _ -> H + He 2_) arld (b) Ionization (H+ + ]le+ -> II+ 4 He 2+ + e). (2) At energies

less than approximately 2.0 - 3.0xlO 5 eV/aJuu the charge exchange process Is

donlinant. Above this energy the ionlzatioll reaction dominates.

(2)-_-'_e cross section o . is defined as the sum of cross sections for all processes

producing slow singly-charged ions plus twice the cross section for producingdoubly-charged slow ions. Similarly the o-cross sect]oil ]s defined as the cross

section for ionization plus the cross section for electron loss or stripping. 111those reactions where electron capture is important, the o _ cross section is the

sum of the lonization cross sectiozl and the electron capture cross section.

Notesz (1) _. and o" are tile stm! of the cross sections for processes producing slowions and electrons, respectively. (2) The reaction channels contributing to theseprocesses are (a) single electron capture; (b) single and double ionization of thetarget atom; (c) single capture plus ionization of the target; (d) capture into Wthe continuum; (e) electron loss; (f) electron ions plus ionization of the target,For He + + He collisions, proceses (c, d and f) are believed to contribute a factor"

of ten less than the ethel processes especially at low energies. (3) For He+energies less than 105 eV/eJ_u, the low-energy o" data of Refs, 104, 105, 355, 364,463, 480, 487, 498, and 500 are not includecJ in the present co,_)ilation.

Notez-- The data of DuBoi8 (Ref. 538) supercede earlier results (Ref. 282) dueto recalibration of the slow recoil ion detector. These corrected data are

consistent with those of Afrosimov et al. (Ref. 148), which define tile low-energy behavior of the cross section.

' , APPENDIX 1

Calculation Of Cross sections and ,Rate coeffioients

from_ Chebyshev Fitti,n,g, ,Parameters

For _ase of numerical data retrieval, the method of least-

squares fitting to the reconunended cross sections and rate

coefficients ,using the Chebyshev orthogonal polynomials has

been used throughout this compilation. In general_ it

produced high accuracy fits to the recommended data.

A measure of the accuracy of the Chebyshev fit representationto the recommended cross sections has been calculated and

appears at the bottom of each cross section page as a relative

rms error with a maximum deviation. In a handful of cases,

the recommended cross sections had associated Chebyshev fits

With an error of greater than 1.00% rms error. These fits

have not been included and only the recommended cross section

data is presented.

The recommended cross-section and rate coefficient data have

been fitted to the following analytical expression:

D £n[a(E) ] = AJ2 + 7. AIT l(X) ,i=l

where k is the smallest number of coefficients that provides

an accurate fit (usually k=6), and

X = [ (£nE - £nEmin) - (£nE,_× - £nE) ] / (£nE_x - £nEmln) ,

and where TI(X ) are the Chebyshev orthogonal polynomials.Fitting to the natural logarithms of the cross section and

energy values increases the Chebyshev fit accuracy by reducing

the ranges of values for the cross section and energy byseveral orders of magnitude.

EThe values of fitting parameters Ai, E_in, and _× are glven foreach reaction after each cross--sectlon or rate-coefficient

table. In each case, the minimum number of parameters A i arelisted which are required to produce a satisfactory fit to the

data. The cross section o is given in units of cm 2, with

collision energies E in units of eV/amu. The rate c:oefficient

is in units of cm3/s, with Maxwellian temperatures T in

units of eV. (We follow the convention used frequently in

plasma physics of expressing temperature in eV energy units,

recognizing that kT is understood, where k is Boltzmann'sconstant.) The analytic representation of the cross section

O or rate coefficient should be used only in the region betweenEmln alld E_ax. The expressions for' the Chebyshev polynomialsare reproauced below for convenience.

TI(x)= XT2(X ) = 2 X2 1

%(x) = 4 x3- 3 xT4(X)= s x4 - 8 X2+ 1Ts(X ) = 16 X5 - 20 X3 + 5 X

T 7_x) = 64 X7 i12 X 5 + 56 X3 7 XTs(X ) = 128 X s - 256 X6 + 160 X4 - 32 X2 + 1

All the rate-coefficient and cross-section data in this volume

may be reproduced by using either of the model Chebyshevfitting programs listed at the end of this Appendix For each

reaction and pair of reactants there are given Chebyshev

fitting parameters to be used as input to the CHEBFOR Fortranor CHEB Basic code.

Irl the iplots of recommended data the Chebyshev or alternative

fits have been added as dashed lines to give a visual

inspection of the accuracy of the fit. Also, the pagescontaining cross section tables include rms deviations of the

fit to the recommended data over the energy range from Emln to

m,_x,

The sample programs listed below Utilize recursion relations

to rapidly generate the Chebyshev polynomials and require

input o f the parameters _moln O, E x' and the Chebyshev

coefficients A0_ Al, A2, ... enable calculation of a rate

coefficient or cross section at a given energy. The programs

direct the user to input these parameters at the proper time

during program execution. To simplify data input, thetabulations of coefficients contain the minimum number of

significant digits required to produce an accurate

representation of the polynomial fit.

The ALADDIN database system may also be used to generate the

cross-section data directly from the fitting coefficients.

See Appendix 2 for details.

ALADDIN 1,2 is an atomic physics database system which hasbeen developed by R. A. Hulse of Princeton Plasma PhysicsLaboratory in conjunction with the Atomic and Molecular DataUnit of the International i\tomic Energy Agency (IAEA) to

provide a broadly-based standard medium for the exchange andmanagement of atomic data. ALADDIN has been adopted by theIAEA as the standard international atomic physics dataexchange format for magnetic confinement fusion applications.

ALADDIN consists _ of a data format definition together

with supporting software for both interactive searches andaccess to the data byplasma modelling and other computercodes. The ALADDIN software has been written in strictFORTRAN-77 to ensure compatibility with the widest possiblerange of scientific computers. The data are stored in

• straightforward ASCII text files either in tabular x,y orparametrized format. Provision has been made _within ALADDINto incorporate the subroutines which are needed to extract theatomic data from each ALADDIN data entry. The Chebyshev

polynomial fits which are presented for the data in thisvolume are one example of such a parametrization.

OAll recommended cross-section data fromthe compilations

in the Atomic Data for Fusion series are available in ALADDIN

format (including those from this volume). Table 2.1 containsa sample ALADDIN data entry from each chapter of this volume.Each entry contains a page-number label to expedite locatingspecificdata within the file. Complete ALADDIN data filesfor this series and a copy of the ALADDIN Database program areavailable on PC-DOS-formatted diskettes from:
