Double-differential neutron-production cross-sections of a thin beryllium target bombarded with 10 MeV protons and deuterons were measured. Neutron energy spectra in the range above 1.8 MeV were obtained by a time-of-flight method at angles of 15, 30, 45, 60, 75, 90 and 120 degrees. Monte Carlo calculations with the PHITS code were performed using the evaluated nuclear data files ENDF/B-VII, the Bertini/GEM model and the JQMD/GEM model, and compared with the experimental results. It was found that the calculated results using ENDF/B-VII and Bertini/GEM for the Be(p,xn) reaction and JQMD/GEM for the Be(d,xn) reaction roughly agreed with the experimental results.
