Calculation of double differential neutron cross-sections of 56Fe and 90Zr isotopes

Systematic analysis of (n,3He) reaction cross sections at 14-15 MeV

Numerous research endeavours have delved into comprehending the dynamics of the (n,3He) reaction cross sections. In this study, a novel and straightforward empirical formula is put forth, aimed at swiftly computing the cross sections of the (n,3He) reaction in the neutron energy range of 14-15 MeV. This new formula has been obtained using outcomes from pre-existing cross section formulas in conjunction with experimental data. The present formulation, hinging on the interplay of A23 parameter, threshold energy (Eth) and incident neutron energy (En) factors, appears to furnish a satisfactory methodology for elucidating the cross sections of the neutron-induced (n,3He) nuclear reaction at 14-15 MeV. Finally, in this paper, a comparison is made between the results of the empirical formula and the experiment.

Analyzing neutron emission cross sections for 22.2 MeV proton-induced reactions on 58Ni and 52Cr

Double differential cross-section calculations were performed for proton-induced reactions with 58Ni and 52Cr isotopes using Monte Carlo code PHITS 3.32 and TALYS 1.96. Comparative analyses with experimental data from the EXFOR library demonstrated the effectiveness of the CTFGM and BSFGM models in conjunction with the TALYS nuclear code program for (p,xn) reactions across all angular values. While the GSM model exhibited consistency regardless of the angle, FLUKA and PHITS showed some discrepancies depending on the angle, particularly at small angle values.
