Abstract
We have studied photon production in heavy-ion collisions at intermediate energies in the Molecular Dynamics approach, where the radiation amplitudes have been derived from the many-body dynamics in the classical bremsstrahlung formalism. This concept allows for a comparison of cross sections obtained by coherent and incoherent summation of amplitudes. The numerical results show a significant enhancement of the coherent cross section for photon energies below 40 MeV due to the dynamical influence of the nuclear mean field.
