Abstract
The exchange interaction between the ionic and the covalent states in the system of two atoms is considered at large internuclear distances. This interaction determines the nonadiabatic transition probabilities in the systems such as A*+B or A++B-. An asymptotically exact expression for this interaction is obtained accounting for the long range (polarization) interaction in the system.Keywords
