Differential cross sections and phase shift analysis of 3He(p, p)3He between 18.0 and 57 MeV
Abstract
Measurements of the elastic differential cross section for 3He(p, p)3He have been made at laboratory energies of 18.0, 20.0, 22.5, 25.0, 27.5, 30.0, 35.0, 40.0, 42.7, 45.0, 48.5, and 57.0 MeV, at angles between 14.1 and 165.0° c.m. A phase shift analysis was performed in the energy range from 18.0 to 35.0 MeV using these data and polarization and spin correlation data from other sources. Angular momenta up to l=4 were used in the analysis, including tensor and spin coupling terms, while inelastic channels were treated through use of complex phase shifts. The results of the analysis exhibit smooth variation with energy, extending and clarifying results obtained at lower energies. Comparisons are made to resonating group predictions of the energy dependence of the singlet and triplet phase shifts.
