Образцы получались посредством распыления жидколитиевого катода дейтериевой плазмой магнетронного разряда. Анализ содержания дейтерия в пленках проводился методом in-vacuo термодесорбционной спектроскопии. После осаждения содержание дейтерия в пленках в среднем D/Li = 15 ат. %. Облучение ультрафиолетовым излучением приводило к образованию дополнительных низкотемпературных пиков десорбции (Т ~ 500 К), а также к исчезновению высокотемпературных (Т &gt; 700 К) или к их сдвигу в более низкотемпературную область. Полученные результаты в перспективе могут лечь в основу методов обнаружения мест преимущественного накопления гидрида лития в токамаках, а также облегчения процесса удаления трития из внутренних элементов термоядерных установок.</p></abstract><trans-abstract xml:lang="en"><p>The effect of UV radiation on deuterium retention in co-deposited lithium-deuterium layers has been investigated. The samples were obtained by sputtering a liquid lithium cathode with a deuterium plasma of a magnetron discharge. The deuterium content in the films was analyzed by in-vacuo thermal desorption spectroscopy. After deposition, the deuterium content in the films averaged D/Li = 15 at %. Irradiation with ultraviolet radiation led to the formation of additional low-temperature desorption peaks (T ~ 500 K), as well as to the disappearance of high-temperature peaks (T &gt; 700 K) or to their shift to a lower-temperature region. In the future, the results obtained may form the basis for methods for detecting the places of predominant accumulation of lithium hydride in tokamaks, as well as facilitating the process of removing tritium from the internal elements of thermonuclear installations.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>тонкие пленки</kwd><kwd>со-осаждение</kwd><kwd>литий</kwd><kwd>дейтерий</kwd><kwd>гидрид лития</kwd><kwd>ультрафиолетовое излучение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>thin films</kwd><kwd>co-deposition</kwd><kwd>lithium</kwd><kwd>deuterium</kwd><kwd>lithium hydride</kwd><kwd>ultraviolet radiation</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке НИОКР “Физико-химические основы разработки литиевых компонент, обращенных к плазме” (FSWU-2025-0004), выполняемого в рамках федерального проекта “Технологии термоядерной энергетики” национального проекта “Новые атомные и энергетические технологии”</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Pitts R.A. et al.
