摘要
Deformed quasiparticle random phase approximation with realistic nucleon-nucleon interactions is employed to investigate beta-decay half-lives and beta-delayed neutron emission probabilities of neutron-rich Kr and Sr isotopes. The residual particle-particle and particle-hole interactions are obtained in terms of the Bruckner G-matrix with the charge-dependent Bonn nucleon-nucleon force. Both allowed Gamow-Teller and first-forbidden transitions are taken into account. The available experimental half-lives are well reproduced with a factor of about three. Predictions on beta-decay properties are made for more neutron-rich isotopes, which could be useful for future experiments.
