Polarization and spin correlation parameters in proton knockout reactions from s1/2 - orbits at 1 GeV

The polarization of the secondary protons (P1,2) in the (p,2p) reaction with the S - shell protons of nuclei 4He, 6Li, 12C, 28Si, 40Ca was measured at 1 GeV unpolarized proton beam. The spin correlation parameters Cij for the 4He and 12C targets also were for the first time obtained. The polarization measurements were performed by means of a two - arm magnetic spectrometer each arm of which was equipped with multiwire - proportional chambers polarimeter.
