  1. Deformation and Convergence Properties of EDF UTK-ORNL DFT group

  2. 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 ?

  3. Results Excitation energy of SD minimum and fission isomer (HFB calculation) LD calculation: assym can be pinned down by calculations in deformed nuclei • 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 Convergence plot of HFB in HO basis HFB calculations:
