Incident-energy dependence of angular distributions of cross section and analyzing power for theNi58(p⃗,He

Abstract

The reaction 58N i(p,3He)56Co to several discrete, low-lying states in 56Co was investigated. Angular distributions of the analyzing power as well as differential cross sections are presented at incident energies of 80, 100, and 118 MeV. Macroscopic zero-range distorted-wave Born approximation calculations are in fairly good agreement with the experimental data in this incident energy range. This has important implications for studies of inclusive reactions in which light composite particles are emitted.

Interplay between multiple intranuclear scattering and pickup in proton-induced emission of3He into the continuum

“…For that reason we have performed a new experiment [4] on 58 Ni(p, 3 He) 56 Co at incident energies of 80, 100 and 120 MeV to address the deficiency. Some preliminary results, other than those presented here, have been reported at various scientific meetings [5][6][7][8]. In this paper we concentrate on the features of cross section and analyzing power angular distributions to discrete final states summed in the excitationenergy range of 0-6 MeV, and evaluate its importance for the understanding of the trend of inclusive proton-induced 3 He emission towards incident energies exceeding about 160 MeV or so.…”
