Abstract

The secondary proton polarization and differential cross sections of the (\(p,p^{\prime}\)) inelastic reaction on nuclei \({}^{9}\)Be and \({}^{90}\)Zr at the initial proton energy of 1 GeV were measured over a wide range of the scattered proton momenta at a laboratory angle of \(\Theta=21^{\circ}\). Scattered protons were detected by means of the magnetic spectrometer equipped with a polarimeter based on multiwire proportional chambers and carbon analyzer. A structure in the polarization and cross section data, related probably to the quasielastic scattering off nucleon correlations in the \({}^{9}\)Be and \({}^{90}\)Zr nuclei, was observed as earlier in the same data for the \({}^{12}\)C, \({}^{28}\)Si, \({}^{40}\)Ca and \({}^{56}\)Fe nuclei. A difference in the momentum distributions of the scattering cross section ratios for the \({}^{90}\)Zr and \({}^{12}\)C nuclei and for the \({}^{90}\)Zr and \({}^{9}\)Be nuclei was observed.
