In this work, the differential cross-sections of 151Eu(γ,n)150Eu and 153Eu(γ,n)152Eu photonuclear reactions in the giant dipole resonance region (GDR) were considered by theoretical models available in Talys 1.8 code. Isomeric ratios of these two reactions induced by bremsstrahlung with end-point energies in (GDR) region were then simulated using the calculated cross-section in combination with Monte-Carlo simulation using Geant4 toolkit based code which was implemented to simulate bremsstrahlung and photonuclear reaction. Moreover, a simple model was added into Geant4 for populating multi-isomeric states. The theoretical results were compared with the experimental data from the existing literature to examine the validity of the theoretical modes.
