dc.description.abstractA nuclear data library has been created for medium energy neutron transport calculations. The 60-group library includes P5 cross sections in standart LASL format for H, B, C, N, O, Si, Fe and W. The 60-group structure was chosen from a sensitivity analysis of a thick iron shield calculated with a 50 MeV deuteron-on-beryllium neutron source spectrum and a 121-group cross-section set. The library combines processed ENDF/B-IV cross-section data below 20 MeV and higher energy cross-section parameters calculated with the intranuclear-cascade and evaporation model. A 6-group version of the library is used in the design of a shield-collimator unit for fast neutron radiotherapy. While the shield is specific for the 50 MeV d+ -Be neutron source presently used in cancer therapy at Texas A&M University, the cross sections and methods developed are applicable to the problems of medium energy neutron shielding in general.en
