Research Abstract

Gamow-Teller transition is one of the most popular nuclear weak processes. The interest in the study is not only of nuclear physics, but also of astrophysics ; it plays important roles in various nucleosynthesis processes such as neutrino-induced reactions in supernova-explosion. Relatively limited information can be obtained through the study of weak processes themselves. However, it was found that charge-exchange reactions, such as (p,n) reaction, can simulate the Gamow-Teller transitions. They could extend the energy region in the study. With the one-order-of- magnitude improvement of the energy resolution in (3He,t) measurements, fine structures of Gamow-Teller excitations, even those of Gamow-Teller giant resonances, can now be studied. Determination of Gamow-Teller transition strengths for pf-shell nuclei with astrophysical interest is discussed.
