Abstract

Energy spectra of protons scattered from a silicon target of natural isotopic composition have been recorded in the angular range of 4° to 40° (lab system). The incident energy was 185 MeV, and the energy range of scattered protons corresponded to a region of excitation energies for 28Si from 0 to 25 MeV. The full width at half maximum of resolved peaks in the spectra was 380 keV.

The differential cross sections measured are presented in graphs giving the angular distributions for the resolved peaks. A qualitative discussion of the excited states which correspond to the observed peaks is presented and is based mainly on the shapes of the angular distributions. Comparisons are made with relevant results from similar experiments.
