The applicability of MCNP6 to simulate quasi-monoenergetic neutron sourcesfrom interactions of proton beams with energies below 150 MeV on thick 7Litargets have been studied. Neutron spectra at zero degrees from a 2-mm 7Lilayer backed by a 12-mm carbon beam stopper in an Al flange bombarded withprotons of 20, 25, 30, 35, and 40 MeV have been calculated with MCNP6 using therecent Los Alamos data library as well as using the Bertini+Dresner andCEM03.03 event generators. A comparison with the experimental neutron spectrashows that the event generators do not do well in describing such reactions,while MCNP6 using the LANL data library simulates production of neutrons from p+ 7Li in good agreement with the measured data.
