Applicability of nuclear reaction models implemented in PHITS to simulations on single-event effects

The nuclear reaction models implemented in the PHITS (Particle and Heavy Ion Transport code System), i.e., the INC model, the QMD model and event generator mode (e-mode) with the JENDL-3.3 are validated to apply it to simulations on single-event effects. The model calculations are compared with available experimental data of light-ion (proton and alpha particle) production from neutron-induced reactions on ^natSi and ¹⁶O for neutron energies below 100 MeV. Since there is no measurement of light-ion production from Si for neutron energies more than 100 MeV, protoninduced reactions on ²⁷Al are also used in the model validation. Comparisons of calculated and measured data for light-ion production show that the e-mode calculation with JENDL-3.3 provides better agreement with the experimental data below 20 MeV than the INC and QMD models, and the QMD model reproduces them well above 20 MeV.
