“…The series of experiments with proton kinetic energies T kin = 280 -2500 MeV at the new cooler synchrotron (COSY) in Jülich promises a wealth of precision data of various hadronic reactions. Among the particle production experiments a systematic study of bremsstrahlung processes is envisaged [1], and the first data with the time-of-flight detector system TOF are analyzed [2]. The interest in bremsstrahlung is as usual for electromagnetic processes in strongly interacting systems: real or virtual photons serve as clean probes of the strong interaction.…”

Within a covariant effective one-boson exchange model for the T matrix of N N interactions we present detailed calculations of bremsstrahlung cross sections for protonproton and proton -neutron reactions at beam energies in the 1 GeV region. Besides pure bremsstrahlung processes we consider photons from ∆ decays and contributions from the η → γγ process. At beam energies above 700 MeV the ∆ decay channel dominates the spectra at large photon energies, where the interference between non-resonance processes and the ∆ decay channel becomes also important. Low energy photons stem from pure bremsstrahlung processes. The available experimental data at 730 MeV beam energy is well described. We extrapolate the model down to 280 MeV, where more detailed experimental data exist, and find agreement with angular distributions.
