gamma induced multiparticle emissions of medium mass nuclei at intermediate energies

A comprehensive analysis of multiparticleemissions following photon induced reactions at intermediate energies is provided. Photon induced reaction is described in the energy range of similar to 30-140 MeV with an approach based on the quasideuteron nuclear photoabsorption model followed by the process of competition between light particle evaporation and fission for the excited nucleus. The evaporation-fission process of the compound nucleus is simulated in a Monte-Carlo framework. The study shows almost no fission events for the medium mass nuclei and reproduces the available experimental data of photonuclear reaction cross sections satisfactorily at energies similar to 30-140 MeV.
