The discovery of a new chemical element with atomic number Z=117 is reported. The isotopes 293117 and 294117 were produced in fusion reactions between 48Ca and 249Bk. Decay chains involving eleven new nuclei were identified by means of the Dubna Gas Filled Recoil Separator. The measured decay properties show a strong rise of stability for heavier isotopes with Z≥111, validating the concept of the long sought island of enhanced stability for super-heavy nuclei

1. Pre-separator (background, short lived isotopes);

2. New detector systems (max. information from single event);

3. New high beam current targets;

4. New radiochemical laboratory, II class (targets preparation,

chemistry of long-lived SHE).

Creation of set-ups will be synchronized with the construction

of the new experimental hall and accelerator.

26

The PAC discussed in detail the programme of the Flerov Laboratory of Nuclear Reactions on the radiochemical studies of superheavy nuclei, proposed by S. Dmitriev.

The programme includes investigations of chemical properties of elements 112–114 in the fusion reactions 243Am+48Са and 242,244Pu +48Са, as well as measurements of isotope masses of these elements with the use of the upgraded mass-spectrometer MASHA.

The PAC notes that the studies of chemical properties of transactinide nuclei play an important role within the framework of the JINR seven-year plan.

The PAC strongly supports the efforts of the FLNR Directorate towards construction of new radiochemical laboratories.

27

Recommendation

The PAC recommends continuation of the study of the chemical properties of superheavy elements with high priority.

The PAC also recommends focusing efforts on designing new radiochemical laboratories.

The PAC recognizes the importance of polarization studies proposed in the GDH&SPASCHARM project, presented by Yu. Plis. The aim of this project is to carry out experimental investigations of a wide scope of problems connected with a QCD spin-flavor structure study of protons and neutrons.

These experiments require the use of polarized targets and beams which determine the key role of the JINR physicists who developed two frozen spin polarized targets to be used in the proposed experimental programme.

The PAC would like to hear at a future meeting a more detailed report about the experimental set-ups.

35

Recommendation

The PAC considers the GDH&SPASCHARM project to be very important and recommends its approval for the years 2011–2013 with high priority.

Experimental study of nuclear fusion reactions in a ptµ system (project TRITON)- D. Demin

R E C O M M E N D A T I O N S 31st meeting (January 2010), PAC for Nuclear Physics

The PAC recommends the development of an experimental project to study ptμ fusion by the Mu-CATALYSIS collaboration (Dubna, VNIIEF Sarov, Delft University, INP Cracow, ITEP Moscow).

37

Experimental investigation of the reactions (1-2) ( ɣ and µ ) was made in the only experiment at PSI : P.~Bauman et al., Phys.Rev.Lett. 24 (1993) 3720 {ptPSI}.

Events of reaction (3) with creation of electron-positron conversion pairs have not been observed by the authors.It turned out that the authors results are in the sharp contradiction with theory. So, the yield of reaction (1) (M1 transition) exceeds the calculated value eight times and the yield of the muon conversion (E0 transition) is higher than expected value by hundreds times!

These reactions proceed from the ground state of the ptµ and hence from the s-waveof the initial system. As the total pt spin can be 1 (initial state) or 0 ( ) and the ground state of is , the possible transitions are (M1) and (E0) .

The rates of the muon catalyzed fusion reactions d+d, p+d and t+t have been measured, and they turned out to be in an agreement with the theory. This is not the case for the p+t fusion rates

38

Proposal for the new experiment to study the pt fusion reactions

We propose to perform the experiment on this subject with new experimental method providing new possibilities for the investigations.

From "the physical" point of view, there are several distinctions between the previous measurement and our proposal.

1. Not triple H/D/T but double H/T mixture will be used that allows to simplify the data interpretation.

2. Our experiment will be especially aimed to detect not only muons and gammas but pairs also, including registration of the electron-positron coincidence in time.

3. Two ways will be used to obtain the relative yields for all three main channels of pt-fusion reaction:a)logical selection criteria using coincidences (anti-coincidences) of the signals for separate parts of the detection system.b) analysis of energy spectra collected by the charge particle detectors.

ee ,

39

TRITON is the continuation of the previous CATALYSIS project. The PAC heard the information by D. Demin on this project to study М1 and Е0 transitions in the pt-fusion reaction in the ptμ molecule. (It is sufficient that М1 transition is sensitive to MEC influence and Е0 to charge distribution in the 4He nucleus.)

The study of the channel yielding е+е- pairs is of special interest. Note that the values of the extracted nuclear matrix elements in the A=4 system are within reach for developing ab initio calculations in modern effective field theory.

It is basically a test of QED under the influence of many-body problems.

Recommendation. The PAC recommends approval of the TRITON project for the years 2011–2013 with high priority.

Formation of strongly deformed nuclear states- A. Zubov

Using the cluster approach, author proposed a model of the hyperdeformed (HD) state formation in the entrance channel of heavy-ion reaction at bombarding energies near and below the Coulomb barrier.

The initial excited (dinuclear system)DNS then can be de-excited by the emission of a neutron to the cold quasibound state which is identical to the HD state. Another mechanism for the population of HD state is the direct sub-barrier tunneling. The neutron emission from the initial excited DNS, which competes with the quasifission and the diffusion of the initial DNS to more symmetric or asymmetric configurations, is described by using a statistical approach. Tunneling through Coulomb barrier is considered using the quantum diffusion approach with the formalism of reduced density matrix.

One can identify the HD state by measuring the consecutive collective rotational E2-transitions in coincidence with the decay fragments of the DNS constituting the HD configuration.

44

The optimal reactions and conditions for the identification of HD states are proposed and the HD state formation and identification cross sections are estimated.

The details are available in the papers: A.S. Zubov, V.V. Sargsyan, G.G. Adamian, N.V.Antonenko, and W. Scheid, Phys. Rev. C 81, 024607 (2010); Phys. Rev. C 82, 034610 (2010).

The PAC also heard with interest the report “Formation of strongly deformed nuclear states” presented by A. Zubov. Improvements and extensions of these calculations are recommended.

The PAC was particularly pleased with the presentations of new results and proposals

by young scientists of BLTP and DLNP in the field of nuclear physics research.
