Doublet and quartet states of Li 2

Abstract

Electronic states of the molecular lithium anion are investigated by configuration-interaction calculations. Comparison with the analogously computed potential energy curves for the lowest singlet and triplet states of the neutral Li2 shows that in addition to the well-known stable ground state X2Σ u + there also exist metastable excited states of Li 2 . Within the quartet sector, two candidates for such long-lived states are identified and their spectroscopic properties studied.
