摘要：
The analyzing power Ay was measured for +-15N elastic scattering at T=164 MeV between 40°and 100°using a polarized NH315 target. Within the statistical accuracy of the data Ay was found to be zero over the full angular range. These data together with differential cross sections from the literature are compared with theoretical predictions based on a momentum-space coupled-channel formalism. While the cross section is very well reproduced there are large discrepancies in the analyzing power for which large spin effects are predicted close to the cross-section minima. Possible deficiencies in the theoretical model are discussed. © 1990 The American Physical Society.
