In violent neutrino‐induced reactions at the core‐collapse stage of type II supernovae, Gamow‐Teller (GT) transitions starting from stable as well as unstable pf‐shell nuclei play important roles. In the β‐decay study of these unstable pf‐shell nuclei, half‐lives can be measured rather accurately. On the other hand, in high‐resolution charge‐exchange reactions at 0°, individual GT transitions up to high excitations can be studied. Assuming the isospin symmetry for the strengths of analogous GT transitions, we present a “merged analysis” for the determination of GT transition strengths starting from proton‐rich nuclei. We applied this analysis to the system, and it was found that the GT transitions and the properties of the β decay can be understood better by combining the mirror GT strength distribution obtained from the reaction.
