Abstract

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.
