Particle transport simulation codes such as PHITS have been used for calculation of radiation shielding in accelerator facilities. In PHITS, INCL describes proton-induced nuclear reactions at intermediate energies of several 100 MeV. Calculated results by the models can reproduce the neutron spectra very well. However, it was pointed out that the calculated results at forward angles underestimate the experimental data in the neutron spectra of lower energies than incident energies by several 10 MeV. In this study, we developed a resonance cross section model considering Isobaric Analog and Gamow Teller resonances on the basis of Evaluated Nuclear Structure Data File (ENSDF). By summing up the result of the model and that of INCL, PHITS can reproduce the experimental data of the proton-induced reaction on Lead targets very well. It is expected that PHITS with the new model gives high accurate results in the calculation of the radiation shielding.

Improvement of intra-nuclear cascade model implemented in PHITS using momentum distribution based on one-particle wave functions

Intra-nuclear cascade model INCL implemented in PHITS can describe various processes occurred by proton-induced reactions at energies of between 10MeV and several GeV. However, INCL overestimate experimental data of proton-knockout reactions. It was pointed out that description of momentum distribution of protons at target surfaces in INCL causes the overestimation. In this study, we improved the momentum distribution by using results of Fourier transformation of simple-particle wave functions. We changed only the component of nucleons in the outer core. In the default INCL, the distribution of surface nucleons has a large component in the high-momentum region. On the other hand, introducing the single-particle model decreases the high-momentum component and suppresses the knockout reaction. By this improvement, INCL can reproduce the data very well. It is expected that PHITS with the improved model gives accurate results of the knockout reaction.
