Systematic study of tensor force effect on pseudospin orbital splittings in Sn isotopes

Abstract

The tensor force effect on the proton pseudospin orbital splittings of the 1 and 1 states in Sn isotopes is systematically analyzed with 36 sets of the TIJ interactions in the framework of the Hartree–Fock–Bogoliubov approach. It is shown that not all tensor parametrizations preserve the pseudospin symmetry.
