Measurement of the polarization correlation parameter C{sub nn} in the pp elastic scattering with an unpolarized proton target and an unpolarized 1-GeV proton beam

Journal Article · · Physics of Atomic Nuclei
The polarization correlation parameter C{sub nn} in the elastic proton-proton scattering was for the first time measured with a high statistical accuracy at 1 GeV using an unpolarized proton beam incident on an unpolarized proton target. Both outgoing protons from the reaction were detected in coincidence by means of a two-arm focusing magnetic spectrometer installed at nonsymmetric angles corresponding to the center-of-mass scattering angle {Theta}{sub cm} = 62.25{sup o}. The correlation parameter C{sub nn}, as well as polarizations P{sub 1} and P{sub 2} of the secondary protons, were measured by means of multiwire proportional chamber polarimeters placed at the focal planes of each spectrometer arm. The obtained data are compared with the predictions of the phase-shift analysis. The connection with the experiment on C{sub nn} and polarization measurements in the (p, 2p) reaction on {sup 4}He and other light nuclei in similar kinematics is discussed
