Pion-nucleus bremsstrahlung offers a possibility of measuring the structure functions of pion-Compton scattering from a study of the small-momentum-transfer region where the bremsstrahlung reaction is dominated by the single-photon-exchange mechanism. The corresponding cross-section distribution is characterized by a sharp peak at small momentum transfers. But there is also a hadronic contribution that is smooth and constitutes an undesired background. In this article the modification of the single-photon-exchange amplitude by multiple Coulomb scattering is investigated as well as the Coulomb-nuclear interference term.
