Abstract

β-decay properties of neutron-rich Ca, Ti, and Cr isotopes are studied within a deformed proton-neutron quasiparticle random-phase approximation. The underlying mean field is described self-consistently from deformed Skyrme Hartree-Fock calculations with pairing correlations. Residual spin-isospin interactions in the particle-hole and particle-particle channels are also included in the formalism. The energy distributions of the Gamow-Teller strength, the β-decay feedings, the β-decay half-lives, and the β-delayed neutron emission probabilities are discussed and compared with other theoretical results, as well as with the available experimental information. The evolution of these nuclear β-decay properties is investigated in isotopic chains in a search for structural changes. A reliable estimate of the β-decay properties in this mass region is valuable information for evaluating decay rates in astrophysical scenarios.
