| Outline of Final Research Achievements |
At the Japan Proton Accelerator Research Complex (J-PARC), we measured the energy spectrum of neutrons emitted from a mercury target irradiated by a proton beam accelerated to 3 GeV in the direction 180 degrees from the beam direction. The measured energy spectrum was found to be in good agreement with that obtained by the latest nuclear reaction model incorporated in the particle transport code PHITS. In addition, a new nuclear reaction model for high-energy fission was proposed and incorporated into PHITS. As a result of comparison with the experimental data, it is shown that the proposed model can reproduce the experimental data more accurately than the conventional model.
