The analyzing power {ital A}{sub {ital y}} was measured for {pi}{sup +}{endash}{sup 15}{rvec N} elastic scattering at {ital T}{sub {pi}}=164 MeV between 40{degree} and 100{degree} using a polarized {sup 15}NH{sub 3} target. Within the statistical accuracy of the data {ital A}{sub {ital y}}({theta}) 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.
