Abstract

The influence of initial dose and irradiation doping upon the recovery of Mo was studied for the markedly different types of damage produced by thermal and fission neutrons.The features of the Stage I recovery commonly seen for several FCC metals can be identified, including a I,, peak at 40°K.The typical dose-dependent behavior of a I_ subpeak was observed at *v* 47°K, and evidence for free interstitial migration is further supported by irradiation doping results.Stage II shows a first-order peak at 120°K in which the population percentage increases with increasing initial dose in opposite fashion to FCC impurity detrapping peaks.
