Projectile and target delta excitation in the (3He, t) and (3He, 3He) reactions

subject

description

Abstract We study simultaneously the ( 3 He , t) and ( 3 He, 3 He) reactions on proton and neutron targets in the region of the delta excitation resonance. We observe that the mechanism of delta excitation in the target dominates the ( 3 He, t) reaction on the proton, but the mechanism of delta excitation in the projectile is important in the ( 3 He, t) reaction on the neutron, and largely dominates the ( 3 He, 3 He) reaction on proton and neutron targets. The two mechanisms give rise to different shapes in the energy distributions of the t or 3 He outgoing particles and the weights and shapes of the mechanism change appreciably with the energy of the projectile. The combined experimental study of both reactions as a function of energy is thus a much richer source of information on the dynamics of these problems than the study of the ( 3 He, t) reaction alone, where the experimental efforts have so far concentrated.
