Optical-emission spectra of coreexcited Be I sL and coreexcited Be I1 ' L and 4L states have been studied by means of the beam-foil-excitation method. Multiconfigurational Hartree-Fock calculations have been performed for the optical transitions between the lower-lying Be I ' L states and between ls2pnl (n = 2-4, 1 = 0-3) 'Po, 'p, 'Do, 'De, and 'P states in coreexcited Be I1 ' L to facilitate the identifications. Some previously assigned core-excited Be I1 4L transitions are shown to belong to either the coreexcited Be I ' L or the coreexcited Be I1 *L spectrum. Additional identifications of core-excited Be I1 'L transitions explain the main features of this spectrum. The identifications of Be I1 ls2p41 4L states are discussed.
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.
