Abstract

The interaction between Li–D films obtained via deposition in magnetron discharge with nitrogen and oxygen is investigated. It is shown that exposure to these gases at a pressure of 4000 Pa does not lead to a significant decrease in the amount of deuterium in the film unlike the case of water vapor. The release of deuterium from Li–D films during thermal-desorption analysis occurs mainly in a narrow temperature range at 650–700 K in the case of as-deposited films and after gas exposure. The amplitude of the low-temperature region in the TDS spectrum increases after oxygen exposure.
