Abstract
We calculate the energy spectra of high energy photons and pions produced in heavy ion collisions at intermediate energies of around 75 MeV/nucleon. We use a unified approach based on the Boltzmann-Uehling-Uhlenbeck theory and the assumption that both pions and high energy gamma rays are produced in individual nucleon-nucleon collisions during the course of the heavy ion reaction. A comparison to existing data for energy spectra of neutral pions and high energy photons shows good agreement.
