Resonant charge exchange involving electronically excited states of nitrogen atoms and ions

Within the framework of the asymptotic theory the matrices for the exchange interaction potentials of the nitrogen ion, with electron shell p2, and nitrogen atom, with electron shell p3, are constructed. The hierarchy of interactions in the nitrogen molecular ion at large internuclear distances is constructed for different electronic states. On the basis of these interaction potentials, the cross sections of resonant charge exchange in slow collisions are evaluated for different values of electron momentum projections and then averaged over these momentum projections. The mobilities of nitrogen ions in atomic nitrogen are also derived.
