Excitation functions were measured for the deexcitation by neutron evaporation of the compound nucleus /sup 200/Po formed in the interactions of /sup 84/Kr+/sup 116/Cd and /sup 40/Ar+/sup 160/Dy. In general, the results are consistent with the predictions of the statistical model of nuclear reactions, including effects of angular momentum and deexcitation by fission. However, few neutron (2n,3n) evaporation is more favored in /sup 84/Kr-induced reactions than in those involving /sup 40/Ar, a result that is not predicted by the statistical model.
