Internal emission and recoil corrections on radiative π+ -proton scattering

Along the line of previous work we calculate the π+ -P radiative scattering cross section at the incoming π+ energies of Tsub(π) = 298, 269, and 324 MeV. The results of the calculation turn out to be in very good agreement with the experimental data for all the energies, showing the great importance of the rescattering and recoil corrections given by the proton motion.
