Elastic and Inelastic Scattering of 14.1-MeV Protons by Medium Weight Nuclei

Abstract

The absolute differential cross sections for the elastic scattering and the inelastic scattering (proceeding to the 1st excited state) of 14.1 Mev protons have been measured for Ni, Fe, Cr and Ti with a five-degree (or less) interval ranging from 20 to 165 degrees. The scattered protons were detected by NaI (Tl) scintillation counter whose energy resolution was about 2.3%. Even at small angles the protons inelastically scattered could be discriminated from those elastically scattered. The angular distributions of inelastic protons agree to that expressed by |j₂(qR)|² which one would expect from the theoretical prediction based upon the Born approximation.
