The secondary-proton polarization and differential cross sections for the (p, p') inelastic reaction on sup.28Si and sup.56Fe 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 = 21degrees. 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.28Si and sup.56Fe nuclei, was observed as earlier in the analogous data for sup.12C and sup.40Ca nuclei. Momentum intervals within which cross- section ratios for nuclei did not depend on the scattered-proton momentum were found. DOI: 10.1134/S1063778818030171
