Inelastic Scattering of Protons on 12C

Abstract

During the recent Variable Energy Cyclotron experiment involving the elastic scattering of protons on 12C, the complete energy spectrum of the scattered protons was obtained by means of a 100-channel analyser (McKenna, Baxter, and Shute 1961, henceforth referred to as I). Two prominent peaks were obtained: the higher energy one corresponding to elastic scattering and the lower energy one to inelastic scattering with the residual carbon nucleus being left in its first excited state, 4· 43 MeV. In I the elastic scattering results were reported briefly. The purpose of this short communication is to discuss the main features of the inelastic scattering.
