Abstract

The rp-process nucleosynthesis proceeds through nuclei near the proton drip-line, in which Gamow-Teller (GT) transitions starting from unstable pf-shell nuclei play important roles. In the beta-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 beta-decay study of the proton-rich nucleus 52Ni and the 52Cr(3He,t) measurement assuming the isospin symmetry of the Tz = +/- 2 -> +/- 1 transitions.
