The scattering of 9.5 MeV protons by He, C, N, O, F, Ne, A, Kr and Xe nuclei

Abstract

A nuclear emulsion method for studying scattering and nuclear reactions of particles from the Nuffield cyclotron of the University of Birmingham, in gaseous targets, is presented. This method has been developed from that described by Burrows, Powell & Rotblat (1951). The differential cross-sections for elastic scattering of 9∙5 MeV protons by He, C, N, O, F, Ne, A, Kr and Xe have been measured, and the results for all except Kr and Xe are discussed in terms of the optical model. Results for carbon obtained at four energies between 9∙37 MeV and 9∙58 MeV show marked dependence on energy. Differential cross-sections for inelastic scattering of 9∙5 MeV protons from C, N, Ne, A and F are also presented and discussed.
