The obtained results were compared with available theoretical and experimental (summarized) data. An important point is related to the accurate accounting of the complex contributions of the exchange-correlation (polarization) effect and the use of an efficient singlequasi- particle representation based on the general relativistic approximation of the quantum defect, which significantly ensures a physically reasonable agreement between the theory and the experiment.ukrelativistic theoryquantum defect methodradiative transitionslithium-like ionsрелятивістська теоріяметод квантового дефектарадіаційні переходилітій-подібні іониArticle
