Study of Inelastic A

The secondary-proton polarization and differential cross sections for the (p, p') inelastic reaction on [sup.28]Si and [sup.56]Fe nuclei at the initial proton energy of 1 GeV were measured over a wide range of the scattered-proton momenta at a laboratory angle of 0 = 21[degrees]. Scattered protons were detected by means of a magnetic spectrometer equipped with a polarimeter based on multiwire proportional chambers and a carbon analyzer. A structure in the polarization and cross section data, which is probably related to quasielastic scattering off nucleon correlations in the [sup.28]Si and [sup.56]Fe nuclei, was observed as earlier in the analogous data for [sup.12]C and [sup.40]Ca nuclei. Momentum intervals within which cross- section ratios for nuclei did not depend on the scattered-proton momentum were found.
