Abstract :
We report a new measurement of analyzing powers for the reaction p ⇒ + CH 2 → one charged particle +X, at proton momenta of 1.75, 3.8, 4.5 and 5.3 GeV / c . These results extend the existing data basis, necessary for proton polarimetry at intermediate energy, and confirm the feasibility of a large acceptance polarimeter based on this process. Particular attention was devoted to the investigation of the optimal target thickness and of the useful angular range. The experiment is performed at the accelerator complex of the JINR-VBLHE (Dubna).
