Abstract

The bremsstrahlung of photons emitted during the scattering of pi(+) mesons off nuclei is studied for the first time. The role of interactions between pi(+) 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(44) Ca.
