Abstract

Owing to its simplicity and also its nature of spin-isospin (sigma tau) excitation, Gamow-Teller (GT) transitions play key roles in the studies of nuclear structure as well as astro-nuclear processes. We studied GT transitions starting from Sc-45 in a high-resolution (He-3, t) charge-exchange reactions at 0 degrees and at an intermediate incoming energy of 140 MeV/nucleon. Individual GT transitions were observed up to high excitation energy of 10 MeV and a concentration of GT strength, a resonance-like structure, was observed at 6.5 MeV.
