Abstract
This work reports the theoretical calculations of cross-section and isomeric ratios (IR) of 119m,gTe, 121m,gTe, 127m,gTe and 129m,gTe generated through bremsstrahlung-induced photonuclear reactions on natural Te target in the Giant Dipole Resonance (GDR) region. The IRs were computed as a function of bremsstrahlung endpoint energies, varying from 10 to 25 MeV. This was accomplished by convolving differential cross-sections calculated by TALYS 2.0 code and bremsstrahlung spectra simulated by the GEANT4 toolkit. To assess the influence of nuclear level density (LD) and gamma strength functions (γSF) on cross-sections and IRs, we computed and evaluated all available LD and γSF models within TALYS 2.0 code, including 60 combinations. The outcomes were compared with experimental data from the EXFOR database, confirming the validity of the GEANT4 and TALYS codes as reliable tools for predicting cross-sections and IRs of Te isotopes in photonuclear reactions within the GDR region. Furthermore, the results highlight the significant role of LD models and γSFs in accurately modeling and estimating photonuclear reaction cross-sections and IRs.
