Calculation of Secondary Neutron Double Differential Cross Sections for Neutron Induced Reactions on Fe with GEANT4 and TALYS

  • The secondary neutron double differential cross sections of iron play an important role in the design, operation and maintenance of nuclear facilities. Reliable nuclear theoretical model and evaluation data are needed in calculation. The secondary neutron double differential cross sections of 8.17, 11.5, 14.1 and 18 MeV neutron induced on iron were calculated with GEANT4 code. The secondary neutron double differential cross sections of 25.7, 65, 100 and 150 MeV neutron induced on iron were calculated with TALYS and GEANT4 codes. Additionally, these calculation results were compared with experimental data. Research shows that, for the energy below 20 MeV, the ENDF/B-VIII.0 library is in good agreement with experimental data, and the BROND-3.1, CENDL-3.1, JENDL-4.0u and JEFF-3.3 libraries show some discrepancies with experimental data. For the energy between 20 and 150 MeV, the calculation results of the BERT model and the TALYS code are in good agreement with experimental data. The calculation results of BIC and INCLXX models are different from experimental data. On the whole, further research is needed for the neutron evaluated nuclear data and nuclear reaction model.
