Experimental Investigation of the Quasielastic Scattering of Polarised Protons on Nuclei at the Jinr VB Lhe Synchrophasotron

Experimental investigation of quasi-elastic scattering of polarised protons on nuclei has been carried out at the JINR VB LHE Synchrophasotron (Dubna, Russia). The analyzing power of proton-nucleus scattering was measured using a beam of stripped polarised protons at 2.5, 3.0 and 3.6 GeV. The goal of the experiment was to test the effect of the analyzing power reduction on proton scattering on intranuclear protons and neutrons, in comparison with scattering on free nucleons.
