Hartree-Fock-Bogoliubov calculations withT=1plusT=0pairing correlations

Abstract

Hartree-Fock-Bogoliubov calculations have been performed for even-even $N\ensuremath{\ne}Z$ isotopes using the Kuo-Brown reaction matrix elements for the Hamada-Johnston potential. The possibility of generalized pairing is explored by considering $T=1$, $T=0$ and $T=1$ plus $T=0$ correlations for the axial and triaxial shapes. It is found that only for the nuclei with $N\ensuremath{-}Z=2$ there is a small contribution by the $T=0$ pairing correlations. Only the $|{T}_{z}|=1$ pairing correlations are important for the ground-state solutions.NUCLEAR STRUCTURE Even-even $N\ensuremath{\ne}Z$ isotopes of Ti, Cr, Fe, Ni, and Zn; calculated ground-state energies using $T=1$, $T=0$, and $T=1+T=0$ pairing correlations; quadrupole moments pickup strengths for the lowest-energy solutions.
