摘要The beta(-) decays of the r-process waiting-point nuclei at the neutron magic numbers N = 50 and N = 82 are investigated within the extended quasiparticle random-phase approximation (QRPA), where neutron-neutron, proton-proton and neutron-proton (np) pairing correlations are considered in the specialized Hartree-Fock-Bogoliubov (HFB) calculation. The Bruckner G-matrix obtained with the charge-dependent Bonn nucleon-nucleon force is used for the residual particle-particle and particle-hole interaction in addition to the pairing interaction. It is found that the np pairing interaction plays an important role in reducing the calculated beta(-)-decay half-lives. The calculations with np pairing show good agreement with the available experimental data including the decay half-lives of Ni isotopes, which are usually overestimated in the self-consistent proton-neutron QRPA calculations.
