    Recent work on molybdenum giving evidence for interstitial and vacancy migration in stages III and IV respectively has been critically examined. Although the suggested annealing scheme is attractive, it is demonstrated that the evidence does not quantitatively support such a model. Alternatively it is argued that other investigations including recent positron annihilation studies point strongly to vacancy migration in stage III. In addition it is proposed that stage IV after neutron irradiation is due to the migration of some small vacancy cluster, possibly the trivacancy or tetravacancy.
