Abstract
Analyzing powers, Ay, were measured at the Clinton P. Anderson Meson Physics Facility for π+ and π- elastic scattering from polarized 13C in the energy region of the [3,3] resonance. The Ay were found to be small in general and, at small momentum transfers, q < 1 fm-1, were reproduced best by a first order optical potential description and standard nuclear wave functions. At large momentum transfer, q ≈1.8 fm-1, present nuclear structure and π-nucleus reaction models do not reproduce the data.
