Description
Spin-isospin excitations in nuclei have been studied by means of the (3He,t) reactions at 450 MeV on the targets 9Be, natC, 28Si, 58Ni, 62Ni, 90Zr, 118Sn, 120Sn, 124Sn, and 154Sm. The new spectrometer ''Grand Raiden'' was employed for the (3He,t) study for the first time. Observed (3He,t) spectra at 0 show remarkable similarity with those from the (p,n) results at intermediate energies, suggesting a simple direct reaction mechanism for the (3He,t) reaction at 450 MeV. The Gamow-Teller (GT) resonances and the spin-flip ΔL=1 resonances are excited very strongly. A fine structure of the GT resonances in medium-heavy nuclei is observed with an energy resolution of 210 keV. It is demonstrated that the (3He,t) reaction at 450 MeV is a powerful tool to study the spin-isospin excitations in nuclei. (orig.)
