    Abstract

    The rp-process nucleosynthesis proceeds through nuclei near the proton drip-line, in which Gamow-Teller (GT) transitions starting from unstable p f -shell nuclei play important roles. In the β -decay study of these nuclei, half-lives can be measured rather accurately. On the other hand, in the high-resolution (3He; t) charge-exchange reactions on mirror nuclei, individual GT transitions can be studied up to high excitations. For the accurate study of the GT transition strengths in the A = 52, T = 2 system, we compare and combine the β -decay study of the proton-rich nucleus 52Ni and the 52Cr(3He; t) measurement assuming the isospin symmetry of the Tz = ±2→±1 transitions.
