Measurement of quasielastic 635 MeV polarized proton scattering asymetry on nuclei of some elements

The dependence of quasielastic 635 MeV polarized proton scattering asymmetry on the target nucleus mass number has been studied with the aim of investigating the influence of nucleon bond in the nuclei on the polarization parameters. The asymmetry for the H, Li, Be, C, Al, Cu, Cd, Pb targets has been measured with 2 telescopes made of scintillation counters with high energetic thresholds of proton registration. The comparison of the results with references polarization data obtained under conditions similar to that of experiment shows that at quasielastic scattering on the nuclei the polarization and symmetry parameters can be essentially different. It is noted that for the complete solution of the problem more accurate measurements are necessary
