    Abstract

    The neutron production ITom galactic cosmic ray (GCR) protons and alpha particles in the lunar subsurface was estimated using the three-dimensional Monte Carlo simulation code PHITS, together with GCR input spectra based on the BESS measurements. The PHITS simulations of equilibrium neutron density profiles in the lunar subsurface were compared with experimental data by Apollo 17 Lunar Neutron Probe Experiment. By use of accurate spectra and nuclear interaction models, our calculations successfully reproduced the data within the experimental error at the shallower region than 300 g/cm2 However, our calculation was up to 30% higher in the deeper region.
