Проведено теоретическое исследование процессов перезарядки при холодных столкновениях атомов рубидия с катионами кальция и иттербия на основе точных квантово-химических данных для адиабатических потенциальных энергий и матричных элементов взаимодействия. В рассчитанных сечениях процессов перезарядки наблюдается резонансная структура, обусловленная туннелированием сквозь центробежный барьер, характерная для режима Ланжевена.
Показано, что в отличие от столкновений Ca+ + Rb в столкновениях Yb+ + Rb доминирующим процессом является излучательная перезарядка.
Ключевые слова: холодные столкновения, перезарядка,неадиабатические переходы, атомы рубидия, катионы кальция, иттербия.
