Study of nucleon correlations in nuclei by (p, p ') inelastic reaction at 1 GeV

The secondary proton polarization, differential cross section, and cross section ratios were measured in the (p, p') inelastic reaction with nuclei at 1 GeV and a laboratory scattering angle of Theta = 21 degrees. The data were obtained over a wide range of the scattered proton momentum covering the pN quasielastic peak and high momentum region up to a momentum corresponding to excited level of the nucleus under investigation. Scattered protons were detected by the magnetic spectrometer equipped with a polarimeter based on multiwire proportional chambers and carbon analyzer. A structure in the polarization and cross section data, possibly related to the in-medium elastic scattering on nucleon correlations arising in nuclei, and a scaling of the scattering cross section ratios of the nuclei were observed in the high momentum range.
