Structure effects in polarization and cross sections for A(p, p’)X inelastic reactions on 40Ca and 12C nuclei at 1 GeV

Abstract

The polarization of secondary protons in the (p, p’) inelastic reactions on ⁴⁰Ca and ¹²C nuclei at the initial proton energy of 1 GeV was measured over a wide range of scattered-proton momenta at a laboratory angle of Θ = 21°. The reaction cross sections were also measured. Scattered protons were detected by means of magnetic spectrometer equipped with a polarimeter based on multiwire-proportional chambers. A structure in the polarization and cross-section data, which is probably related to scattering off nucleon correlations in the nuclei involved, was observed.
