On the interaction of Li–D films with nitrogen and oxygen at room temperature

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.
