Abstract
The bremsstrahlung of photons emitted during the scattering of mesons off nuclei is studied for the first time. The role of interactions between mesons and nuclei in the formation of the bremsstrahlung emission is analyzed in detail. We discover an essential contribution of photons emitted from nuclear part of the Johnson–Satchler potential to the full spectrum, in contrast with the optical Woods–Saxon potential. We observe an unusual essential influence of the nuclear part of both potentials on the spectrum at high photon energies. This phenomenon opens a new experimental way to study and check non-Coulomb and nuclear interactions between pions and nuclei via measurements of the emitted photons. We provide predictions of the bremsstrahlung spectra for pion scattering off .
