Abstract

Analyzing powers Ay were measured for + and - elastic scattering from polarized C13 at incident pion energies T near the P33 -nucleon resonance. At T=130 MeV, the values of Ay are significantly different from zero for - scattering. For + at T=130 MeV and for both - and + at all other energies, the Ay are mostly consistent with zero. Elastic differential cross sections were measured using an unpolarized C13 target. Both the analyzing-power and cross-section data were compared with predictions using a variety of nuclear structure and reaction models. The analyzing power was found to be strongly sensitive to the quadrupole spin-flip part of the transition. The data of this work complement measurements of the magnetic form factor by electron scattering. The pion Ay data are not reproduced by calculations using wave functions that fit the magnetic form factor at low momentum transfers.
