The combined relativistic energy approach and relativistic many-body perturbation theory with the zeroth order ab initio model potential optimized one-particle representation are used for precise computing the energy levels and radiative decay probabilities (radiation amplitudes) of heavy alkali elements, in particular, there are listed data for the 7s 1/2-np 1/2 , 3/2 , np 1/2 , 3/2-nd 3/2 , 5/2 (n=7-10) transitions in Fr and some E1 and E2 transitions in a single ionized Hg + atom. The comparison of the calculated values with available theoretical and experimental (compillated) data is performed..
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
