摘要

The secondary proton polarization and differential cross sections of the (p, p') inelastic reaction on nuclei Be-9 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 degrees. 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 Be-9 and Zr-90 nuclei, was observed as earlier in the same data for the C-12, Si-28, Ca-40 and Fe-56 nuclei. A difference in the momentum distributions of the scattering cross section ratios for the Zr-90 and C-12 nuclei and for the Zr-90 and Be-9 nuclei was observed.
