摘要：
Left-right asymmetries for pion elastic scattering and charge exchange from polarized C-13 and N-15 are calculated and compared with the available data. It is shown for elastic scattering that the quadrupole spin-flip contribution is dominant in the determination of the asymmetry at forward angles. The distorted wave impulse approximation and optical model treatments are compared and a qualitative discussion of the underlying physics of the sign of the asymmetry in the first diffraction minimum is presented.
