Abstract
Photons originating from coherent bremsstrahlung have been measured over a large dynamic range for the reaction of 200 MeV particles with protons. At low photon energies the bremsstrahlung spectrum exhibits the classical behavior with an approximate shape. At higher photon energies there is a pronounced contribution from capture into the unbound ground state and first excited state of . These results allow one, for the first time, to test theoretical models for a consistent description of bremsstrahlung and radiative capture in a complex system. Calculations predict both features qualitatively but fail to account for their relative importance.
