PROTON-NEUTRON PAIRING IN LIPKIN-NOGAMI APPROACH

摘要

State-dependent δ-force is used to analyze isovector (T = 1) and isoscalar (T = 0) superfluidity in the framework of the generalized BCS model with an approximate Lipkin-Nogami particle-number projection. Calculations are performed with the single-particle levels generated in axi-ally symmetric Skyrme-Hartree-Fock code with SIII force for several medium-mass N ～ Z nuclei.
