Quasi-elastic scattering of proton with 1 GeV energy on eight-nucleon cluster inside nucleus

Abstract

Available data on the polarization of the secondary proton (as a function of its momentum $K$) in the inelastic ({\it p, p${}^{\prime }$}) reactions with the ${}^9$Be, ${}^{12}$C, and ${}^{40}$Ca nuclei and differential cross section data (the momentum distributions) for the reactions at the initial proton energy 1 GeV and scattering angles $\Theta$=21${}^{\circ }$ and $\Theta$=24.5${}^{\circ }$ were analysed in a range of the high momenta $K$ close to the momentum corresponding to the proton elastic scattering off the investigated nucleus. A structure in the polarization and momentum distribution data at the high momenum $K$, related probably to quasi-elastic scattering off a ${}^8$Be-like nucleon cluster inside the nuclei, was observed.
