A comparison is made between results of recent neutron- and ion-irradiation experiments on metals. Specifically, lowtemperature defect production and stage-I annealing are discussed. Defect production efficiencies observed for neutron irradiations are shown to be consistent with results for ion irradiations. A phenomenological model describing both defect production and stage-I annealing in terms of thermal-spike induced recombinations is introduced. The stage-I recovery fraction for ion and neutron irradiations is found to correlate with cascade-energy density as represented by an appropriate nuclear stopping power.
