Analysis of neutron capture cross section using different level density models on cadmium isotopes up to 250 keV neutron-induced energy and GEANT4 simulation

The neutron capture cross-sectional reactions for 106,108,110,111,112,113,114,116Cd isotopes have been calculated with different level density models which are constant temperature Fermi gas (CTFG) model, back-shifted Fermi gas model, generalized superfluid model and Hartree-Fock-Bogoliubov model by using TALYS 1.9 and EMPIRE 3.2 codes for incident neutron energies up to 250 keV. The obtained results have been analyzed with each level density model parameters existing in Reference Input Parameter Library (RIPL-3) and available experimental data. As an outcome, to obtain more precise and coherent calculations with the experimental values, level density model and its parameters have been determined. Also, hadronic interactions of low-energy neutrons have been investigated for a situation by using GEANT4.
