Abstract
Single crystals and rolled foil of Mo with and without predamage by 11 or 18 keV 4 He at room temperature have been injected with 8 or 16 keV H and D isotopes. The H depth profiles and the total D retention were measured by nuclear microanalysis techniques. A strong enhancement in the trapping of hydrogen isotopes after He predamage over Mo without predamage is observed and the H depth profiles scale with the He ion energy. Cold work increases the D trapping in the absence of He damage but after 3 × 10 15 He/cm 2 predamage little difference remains in the total trapping for single crystals and rolled foil. The release of the D upon annealing due to detrapping occurs primarily between 100 and 450°C. A similar fractional reduction in trapping is observed for elevated temperature D injection as is found in the anneal to corresponding temperatures of room temperature injected samples.
