Abstract

The Geant4 photonuclear process is benchmarked by comparing it with experimental data to verify the ability of the Geant4 toolkit to simulate the photo-induced reaction on deformed nuclei in the Giant Dipole Resonance (GDR) region. The simulation results are compared with experimental data of the deformed nuclei (153Eu, 160Gd, 165Ho, and 186W) targets in terms of both the average neutron energies and the photonuclear cross-sections. The agreement between the calculated results of the Geant4 photonuclear process model and the experimental measurements is analyzed.
