Nuclear modeling of the 239Pu(n,xn) excitation function

Calculated excitation functions for the (n,2n) and (n,3n) reactions on 239Pu are presented. In these calculations precompound plus compound decay models with experimentally deduced fission probabilities are used. A range of results are presented indicating the uncertainty in the model calculations. Experimental measurements which would constrain the range of modeled result are suggested. 21 references
