MCNPX calculation was performed based on the nuclear data libraries of LA150,<br />
TENDLE-2009 10) , and the implemental models, an intranuclear cascade model (Bertini 11) ) and<br />
an evaporation model (Dresner 12) ). The calculation results generally reproduce the measured<br />
energy spectra, considering that these models are initially intended for use in the high-energy<br />
nuclear reaction with energies above 100 MeV.<br />
