Potential energy curves of 58 states of Li-2(+)

Adiabatic potential curves for all electronic states correlated to Li++ Li[ 2s] up to Li++ Li[6g] have been computed in the framework of a model potent ial method, over a rather large range of internuclear distances (4 a.u. < R < 40 a.u.). A good agreement has been obtained with previous theoretical d eterminations as well as with available experimental results for the ground and the first excited states. Long-range-type predictions for the lowest s tates have been considered. (C) 1999 Elsevier Science B.V. All rights reser ved.
