The effective 3he-nucleon force in a microscopic DWBA approach to the ( 3He, t) charge-exchange reaction

Abstract

The ( 3He, t) reaction has been studied on the targets 12C, 16O, 24Mg, 26Mg, 28Si, 32S, 42Ca, 48Ca, 54Fe, 58Ni and 90Zr at incident energies 66–90 MeV. From angular distributions of transitions to selected states the parameters V ρ , V σρ , V Tρ and V LSρ of an effective projectile-nucleon force parametrized with single Yukawa potentials have been obtained for this energy domain. Differences from the force proposed earlier by Schaeffer for a lower energy are found, notably in the tensor component.
