Photonuclear reactions on stable isotopes of cadmium and tellurium at bremsstrahlung end-point energies of 10−23 MeV*

Abstract In this study, the γ-activation approach was used to conduct tests at the bremsstrahlung end-point energies of 10−23 MeV by utilizing the MT-25 microtron beam. The experimental values of the relative yields and cross sections per equivalent quantum of photonuclear reactions on the stable isotopes of cadmium and tellurium were compared with the theoretical calculation results obtained from TALYS-2.0 using the default parameters and the combined model of photonucleon reactions (CMPR). The inclusion of isospin splitting in the CMPR allows for the definition of experimental data on the proton escape reactions with energies ranging from 17 to 23 MeV. Therefore, isospin splitting must be considered to accurately describe the decay of the giant dipole resonance. For Cd isotopes, essential discrepancies of yet unclear origin between theory (TALYS 2.0 and CMPR) and experimental data are found in the neutron channel.
