“…The last update (IAEA/PD-2019.2) was released in October 2022 [18]. In 2022, Bakhtiari and colleagues [15] studied the production of photoneutrons by irradiating 16.6 MeV monoenergetic photons to gold, lead, tin, and copper targets using the MCNP6.1, FLUKA and PHITS codes. They showed that different codes produce relatively different results due to the use of various models and photoneutron cross-sections.…”

“…Deuterium and beryllium nuclei are interesting due to their low energy threshold (2.22 MeV and 1.67 MeV, respectively) for photonuclear interactions [10]. Many simulations have been performed using different Monte Carlo codes (such as GEANT4 [11], MCNP [1,12], FLUKA [13,14] and PHITS [15], etc) to generate photoneutron sources through an electron LINAC. In ref [11], the authors simulated a photoneutron source through a 10 MeV electron beam using the GEANT4 code.…”

In the present study, photoneutron production using a 5 MeV electron linear accelerator (LINAC) was investigated based on new photoneutron cross-sections (IAEA/PD-2019.2) from the International Atomic Energy Agency (IAEA). A detailed reconsideration of a past study has been done in order to make a photoneutron source based on a heavy water target. In this regard, new cross-sections of deuterium and beryllium were added to the library of the MCNP6.1 Monte Carlo code for the simulation of photoneutron production. In addition, the FLUKA4-3.0 Monte Carlo code was employed for comparison and data validation. Moreover, the obtained results from those two codes (MCNP and FLUKA) were compared and discussed with the theory and the previous study. Finally, it is concluded that the simulation of photoneutron production through an electron LINAC can have relatively different results based on the photoneutron cross-sections and even on the Monte Carlo code used. Therefore, a special attention should be paid to the difference between photoneutron cross-sections as well as the difference in Monte Carlo codes to maintain reliability.

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