Gamow–Teller transitions in exotic pf-shell nuclei relevant to supernova explosion

    Research outputpeer-review


    Gamow–Teller (GT) transitions starting from 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.
