Abstract The exciton model in its closed form and the Weisskopf-Ewing model have been consistently applied to neutron-induced reactions. The analysis has been performed for 12 nuclei in the rangeA=45–209. The primary particle-emission is considered to be governed by an admixture of precompound and compound-nucleus mechanisms, while all consecutive particles are considered to undergo pure compound-nucleus emission. The calculated primary-neutron spectra and excitation functions for (n, p), (n, 2n) and (n, 3n) reactions atE n=4–24 MeV have been compared with experimental data. The average best-fit values of the exciton-model free parameterK have been found to be ¯K=700 MeV3. Departures form this value appear to cancel out structure effects introduced into transition rates through the structure-sensitive single-particle level density.
