Scientific paper

The cross section for the N(3 plus)-H charge exchange reaction is calculated within the framework of the molecular model of atomic collisions. The potential energy curves of the NH(3 plus) molecular ion are determined by a model potential method. The scattering equations describing the collision are derived in a fully quantal approach and solved to obtain the S-matrix. For temperatures less than 400 K, the reaction rate remains fairly constant of the order of 2-3 x 10 to the -10 cu cm/s (a minimum of 2 x 10 to the -10 cu cm/s occurs at 300 K). For temperatures exceeding 400 K the reaction rate increases with T, attaining 8 x 10 to the -9 cu cm/s at 30,000 K.
