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 X there also exist metastable excited states of Li. Within the quartet sector, two candidates for such long-lived states are identified and their spectroscopic properties studied.
