Özet

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