Pseudo-spin symmetry in density-dependent relativistic Hartree-Fock theory

Nuclear Theory 2009-11-11 v1

Abstract

The pseudo-spin symmetry (PSS) is investigated in the density-dependent relativistic Hartree-Fock theory by taking {the} doubly magic nucleus 132^{132}Sn as a representative. It is found that the Fock terms bring significant contributions to the pseudo-spin orbital potentials (PSOP) and make it comparable to the pseudo-centrifugal barrier (PCB). However, these Fock terms in the PSOP are counteracted by other exchange terms due to the non-locality of the exchange potentials. The pseudo-spin orbital splitting indicates that the PSS is preserved well for the partner states \lrbν3s1/2,ν2d3/2\lrb{\nu 3s_{1/2}, \nu2d_{3/2}} of 132^{132}Sn in the relativistic Hartree-Fock theory.
