Within the framework of the asymptotic theory the matrices for the exchange interaction potentials of the nitrogen ion, with electron shell p{sup 2}, and nitrogen atom, with electron shell p{sup 3}, 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.
