We report here a new measurement of analyzing powers for the reaction $\\vec p+CH_2\\to one charged particle +X$, at proton momenta of 3.7, 4.5 and 5.4 GeV/c. These data extend the existing data basis, necessary for proton polarimetry at intermediate energy, and confirm the feasability of an extended polarimeter based on this inclusive reaction. The experiment is performed at the accelerator complex of the JINR-LHE (Dubna). |
