摘要：
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 beta-decay study of these pf-shell nuclei. half-lives can be measured rather accurately. On the other hand. in high-resolution (He-3, r) charge-exchange reactions at 0 degrees, individual GT transitions up to high excitations can be studied. Assuming the isospin symmetry for the strengths of T-z = +/-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.
