Further Investigation of Two-Body Interactions in Hartree-Fock Calculations

Hartree-Fock calculations with two-body forces are presented in several nuclei, taken as spherical, from He4 to Pb208. We first present the results obtained with the best (SP1 and SP2) of the recent smooth semirealistic interactions of Saunier and Pearson. These yield good binding energies and radii except in the vicinity of Ni56. However, the spectra in nuclei with spin-unsaturated shells are poor: The spin-orbit splittings in such nuclei are …
