Angular Distributions of Elastically and Inelastically Scattered Protons from Indium

Thin targets of natural indium were bombarded with 7.04-Mev protons, and the scattered particles were analyzed with a magnetic spectrograph. Inelastically scattered protons were observed corresponding to excited states in ${\mathrm{In}}^{115}$ at 1.078, 1.135, 1.292, and 1.982 Mev. Measurements were made on the variation of the absolute cross sections for elastic and inelastic scattering, and it is concluded that a direct interaction process is important in the excitation of these states.
