Abstract
A total of thirty-three angular distributions of elastically scattered protons have been measured in the energy range from 3.49 to 6.42 Mev with the targets V, Cr, Fe, and Co. It was observed that the angular distributions measured with V and Co have similar shapes at all energies. Likewise the angular distributions with Cr and Fe are similar, but qualitatively different from those with V and Co. By using the optical model it has been possible to obtain fits to some of the data for V and Co, but the large cross section at large angles prevents an adequate fit to the Cr and Fe data. Calculations are presented which indicate that this failure of the optical model is due to the presence of compound elastic scattering from Cr and Fe.Keywords
