Effect of Dynamical Pairing of the Beta-Decay Properties of Neutron-Rich Nuclei

Resumo

The influence of an effective spin—isospin interaction in the particle—particle channel on the beta-decay half-lives and multineutron-emission probabilities is studied. The contributions of tensor correlations and coupling of the one- and two-phonon configurations are taken into account within a self-consistent approach that relies on the quasiparticle random-phase approximation and which employs Skyrme interaction. The beta-decay properties of neutron-rich cadmium isotopes are calculated.
