Transcript of Deformation and Convergence Properties of EDF UTK-ORNL DFT group.
Microscopic Liquid Drop
Two aspects:
Surface-symmetry coefficient varies wildly from one interaction to another can we constrain it better by using data from deformed nuclei ?
Considering the theoretical (basis truncation) and experimental error, how reliable such a fit would be ?
Results
HFB calculations:
LD calculation: assym can be pinned down by calculations in deformed nuclei
Excitation energy of SD minimum and fission isomer (HFB calculation)
Convergence plot of HFB in HO basis
Future work:
Wrap up the results
Remove shell contribution to “compare apples with apples”
Try to correlate assym values with results for E*
Would be nice to have values of assym for more forces
