There is a growing interest in the use of accelerator-based neutron sources for scientific and medical applications. For neutron source design, computer codes that can evaluate neutron yields are indispensable; PHITS (Particle and Heavy Ion Transport code System) is one of suitable candidates. In this study, we proposed a new nuclear reaction model based on INCL coupled with the DWBA calculation for an accurate calculation of neutron yields. The DWBA calculation describes discrete peaks in neutron spectra. Although these peaks are not the major part of neutron sources, the estimation of their contributions is necessary, since neutrons from the peaks have high energies close to those of the incident particle. We will present the calculation method of our approach and results for proton and deuteron induced reactions on Li, Be, and C targets at incident energies from 10 to 100 MeV.
