The effects of the residual interaction in the particle-particle channel on β-decay characteristics and the multi-neutron emission probabilities in the β-decay of 130;132Cd are studied within the quasiparticle random phase approximation with the Skyrme interaction. The coupling between oneand two-phonon terms in the wave functions of the low-energy 1+ states of the daughter nuclei is taken into account. It is shown that the inclusion of the spin-isospin interaction in the particle-particle channel leads to the reduction of half-lives and redistribution of one- and two-neutron emission probabilities. The competition of tensor interaction and neutron- proton pairing contribution in β-decay characteristics of the neutron-rich Cd isotopes is discussed. [ABSTRACT FROM AUTHOR]

The Qβ-window has been studied within the Skyrme HF-BCS calculations including the blocking effect of unpaired neutron and proton in cases of the even-odd and odd-odd nuclei. Using the energy-density functional T45 containing the tensor terms, we analyze this effect on the β-transition rates of the neutron-rich nuclei 72-80Ni. [ABSTRACT FROM AUTHOR]
