摘要: We investigate the effects of Coulomb force on nuclear pairing properties by performing Gogny Hartree-Fock-Bogolyubov calculations for N=20, 28, 50, 82, and 126 nuclei. The reduces proton pair energy even-odd mass difference about 25%, except nuclei at around shell or subshell closure. then propose a renormalization scheme via reduction factor {gamma}{sub p} channel. It is found that single value p}=0.90 accounts well Coulombic effect covering wide range number neutron excess, including
