Abstract
Gamow‐Teller (GT) transitions starting from stable as well as unstable pf‐shell nuclei are of interest not only in nuclear physics, but also in astrophysics, e.g. in violent neutrino‐induced reactions at the core‐collapse stage of type II supernovae. In the β‐decay study of these pf‐shell nuclei, half‐lives can be measured rather accurately. On the other hand, in high‐resolution (3He,t) charge‐exchange reactions at 0°, individual GT transitions up to high excitations can be studied. Assuming the isospin symmetry for the strengths of Tz = ±1→0 analogous GT transitions, we present a unique “merged analysis” for the determination of absolute B(GT) values. This method can be applied not only to T = 1 systems, but also to higher T systems.
