Abstract
A Lagrangian isobar model is used to calculate polarization asymmetries for pion-proton radiative scattering. Numerical results are presented for incident pions of 298 MeV kinetic energy and various coplanar and noncoplanar kinematical situations. It is found that the asymmetry calculations are sensitive to the structure of the interaction even at low photon energies, and thus may present a better way of studying structure effects than has been the case with differential cross sections.
