Title: Proton-Neutron Correlation Energies From Self-Consistent Large-Scale Mass Calculations

Abstract

Proton-neutron correlation energies extracted from double differences in binding energies, obtained from theoretical masses calculated within the Skyrme density functional theory with contact pairing interaction, are compared with experimental values based on the 2003 nuclear mass compilation. It is shown that theory gives a qualitative (and often quantitative) reproduction of experiment. The agreement is particularly good for deformed nuclei. For transitional systems, the comparison suggests that more theoretical work is required to incorporate dynamic correlations that go beyond the mean-field theory.
