Abstract

A calculation of energetic photon production in proton-nucleus reactions at intermediate bombarding energies is performed assuming the first chance nucleon-nucleon collisional mechanism. The elementary nucleon-nucleon bremsstrahlung amplitude is calculated within a meson exchange potential model which includes the one-body as well as the two-body current contributions. The results are in reasonable agreement with the recent data by the Grenoble group at the proton incident energy of Tlab=168 MeV and indicate that these energetic photons are created in a relatively low-density region in the nucleus (∼40% of the nuclear matter normal density). The present model, however, cannot account for the strong angular dependence observed at Tlab=72 MeV.
