Comparison of double-differential cross-section between nuclear data library and experimental data for photoneutron production

In this study, we compared double differential cross-sections (DDXs) between the experimental data obtained by 16.6 MeV of polarized photons and DDXs from JENDL2004 JENDL/PD-2016.1 for 197 Au, nat Pb, Cu, Ti targets. Using Python-based software, extracted nuclear libraries (NDLs), which were subsequently deduced considering abundances each target’s isotopes, width photon beam, energy resolution neutron detectors. For target, DDX consistent with that NDLs. Cu targets, at energies higher than 4 larger values The inconsistency those NDLs indicates need to improve physical models generate spectrum photoneutrons.
