Theoretical studies of nonresonant charge-transfer processes using a multistate molecular wave-function approach: Li+Na+Li++Na

The charge-transfer processes for the collisions Li+Na+→Li++Na and Na+Li+→Na++Li have been studied theoretically using the first six molecular states in a multistate impact-parameter approach (using the Born-Oppenheimer breakdown terms to couple the states). The results lead to a rather simple description of the charge-transfer process involving primarily transitions between the 1+2 and 2+2 states and between the 2+2 and 1Π2 states of the LiNa+ quasimolecule.
