Photonuclear reactions on stable isotopes of selenium at bremsstrahlung end-point energies of 10-23 MeV

In this study, experiments were performed at bremsstrahlung end-point energies of 10-23 MeV with the beam from the MT-25 microtron using the gamma-activation technique. The experimental values of relative yields were compared with theoretical results obtained on the basis of TALYS with the standard parameters and the combined model of photonucleon reactions. Including isospin splitting in the combined model of photonucleon reactions allows describing experimental data on reactions with proton escape in the energy range from 10 to 23 MeV. Therefore, taking into account isospin splitting is necessary for a correct description of the decay of the giant dipole resonance.
