The effect of the unpaired nucleons on the β-decay properties of the neutron-rich nuclei

[摘要] Starting from the T45 Skyrme interaction with tensor terms the properties of the β-decay of72-80Ni are studied. We take into account the effect of unpaired neutron and proton on the ground state properties of odd-odd and even-odd nuclei. It is shown that the calculated Qβ-values and the β-decay half-lives are in a reasonable agreement with experimental data.
