Nuclear weak response from the combined study of beta-decay and charge-exchange reaction

Abstract : Studying the weak nuclear response, especially the Gamow-Teller (GT) transitions, of stable as well as unstable pf-shell nuclei, is one of the key issues in nuclear and astro- nuclear physics. We study the decay half-lives and the GT transitions starting from Tz = 1 and 2 mirror nuclei, respectively, by means of decays and complementary hadronic (3He; t) charge-exchange reactions. Under the assumption that isospin is a good quantum number, symmetry is expected for mirror nuclei and the GT transitions starting from the mirror nuclei. The half-lives and branching ratios and the measured strength distributions of GT transitions are compared and also combined for the understanding of the nuclear structure of pf-shell nuclei far-from-stability.
