Analysis of Proton-Nucleus Scattering at 9.8 Mev

Abstract

Studies of nuclear scattering from an arbitrary complex central potential have been initiated. This first report is devoted to the analysis of proton-nucleus scattering at 9.8 Mev using the Saxon potential. Qualitative rules for the dependence of the cross section on the parameters of this model are presented for mediumheavy elements. An important feature of the analysis is that more than one set of optical model parameters is possible at this energy. These multiple solutions have in common approximately the same value of VR 2 , where V is the real part of the nuclear potential and R is the interaction radius. This value does not differ significantly from the value used in the nuclear shell model. The imaginary part of the nuclear potential corresponds to an absorption length of about one nuclear radius.

Reaction Mechanism in Inelastic Scattering of Protons from Mg, Cr, and Other Elements from 3.5 to 7 Mev

“…Angular distributions from some a-particle reactions are well fitted by this simple model. 6,7 A more sophisticated DI calculation in which the above three assumptions were dropped has been done by Levinson and Banerjee. 8 Optical-model wave functions were used for incident and scattered waves and shell-model wave functions for the initial and final states.…”

“…The most recent and comprehensive applications of this model to proton scattering have been made by Melkanofl, 6 Glassgold,7 and their co-workers.…”
