{Large γ} induced multiparticle emissions of medium mass nuclei at intermediate energies

A comprehensive analysis of multiparticle emissions following photon induced reactions at intermediate energies is provided. Photon induced reaction is described in the energy range of $\sim 30-140$ 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 satisfactorily well the available experimental data of photonuclear reaction cross sections at energies $\sim 30-140$ MeV.
