Abstract

Data are presented for the (He3, t) reaction at energies of 600 MeV, 1.2 GeV, and 2 GeV on targets Cnat, Fe54, and Y89. The low-excitation-energy regions of the spectra are dominated by isospin-spin excitations. Cross-section calculations in distorted-wave impulse approximation with parameters from NN data account reasonably well for the data. At 2-GeV bombarding energy a strong excitation of the Δ resonance is observed for all targets.
