Abstract

Absolute values of the polarization in p-12C elastic scattering have been measured at 60.0 and 64.5 MeV at 47.5° in the laboratory system using a double scattering method and a method to measure an asymmetry with a polarized beam. The results are P(60.0 MeV, 47.5°) = 0.965 ± 0.011 and P(64.5 MeV, 47.5°) = 0.975 ± 0.11. Based on these values, the polarization measurements have been extended to the energy range from 40-75 MeV at several angles round 47.5° using the polarized proton beam and the energy degrader. Differential cross sections and polarizations from 15-115° are also presented at 65 MeV. These data will be valuable for the monitoring of beam polarization in this energy region.
