Description

We have calibrated the analyzing power Ay in proton-carbon elastic scattering at 71.2 MeV via double-scattering with polarized beam. An accuracy of ±0.001 was achieved using a highly efficient setup (statistical uncertainty of ±0.0003) and a new type of analysis based on asymmetry ratios. Our result Ay=0.986±0.001 may indicate the existence of a point with Ay=1 near 65 MeV. (orig.)
