Abstract

The Gamow-Teller transition strengths in pf-shell nuclei are important parameters in a presupernova model. A high resolution (He-3,t) reaction was performed from T-z = +1 nuclei (Ca-42, Ti-46, Cr-50 and Fe-14) to T-z = 0 nuclei ((SC)-S-42, V-46, Mn-50 and Co-54) at an incident energy of 140 MeV/nucleon and at 0 degrees for the precise study of GT transition strengths B(GT). To derive B(GT) values for these pf-shell nuclei, the R-2 value, the ratio between the GT and Fermi unit cross sections, was introduced. The R-2 values were studied for various mass nuclei by using the B(GT) values from beta-decay studies as standard, and the mass dependence was derived. It was found that GT strengths in these four pf-shell nuclei move to higher excitation energies as the mass number A increases. The obtained GT strength distributions were compared with shell model calculations.
