Deformation and Convergence Properties of

EDFUTK-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
