Measured neutron emission spectra from 14-MeV neutron-induced reactions in a wide range of nuclei are analyzed by precompound nuclear model calculations. The nuclear model code parameters are adjusted using a least-squares fitting procedure to optimize the agreement between calculation and experiment, but the parameters are constrained to physically reasonable values. A single set of input nuclear constants produces calculated spectra that agree to within 30% of experimental values in over 70% of the cases.
