Abstract

Due to the simplicity of the στ operator that causes Gamow-Teller (GT) transitions, they are the most popular nuclear weak process in the Universe. The GT transitions in pf-shell nuclei, for example, starting from stable Tz=+1 and proton-rich Tz=+1 nuclei, where T z=(N-Z)/2, play important roles in the supernova-explosion or rp-process nucleosynthesis. In the β-decay study of pf-shell nuclei, half-lives can be measured rather accurately. On the other hand, in a high-resolution (3He, t) charge-exchange reaction at 0°, individual GT transitions up to high excitations can be studied. In order to derive reliable GT transition strengths B(GT), we present a unique analysis that combines the strength distribution form the (3He, t) measurement with the information from the study of mirror β decay, where good isospin symmetry of Tz=±1→0 transitions is assumed. © 2010 American Institute of Physics.
