Abstract
Measurements have been made of the polarization and the angular distribution of 424-Mev protons elastically scattered from carbon, aluminum, iron, and silver. The results clearly indicate the importance of separating the elastic scattering from scattering involving excited states of the nucleus. By the inclusion of inelastic scattering, the dips in the cross-section curves and the details in the polarization curves get smeared out. The carbon data show reasonable agreement with similar work by Chesnut. Elastic cross sections were estimated by extrapolating the differential cross-section curves to zero degrees using the optical model of the nucleus.
