Abstract : The general description of proton-homonuclear diatomic molecule collisions is formulated in impact parameter language. A solution of the resulting Schroedinger equations through the second iteration is used for the ab initio calculation of the proton-nitrogen charge exchange cross section. The agreement with experiment is essentially exact although this may be fortuitous. The first iterative solution is used to compute the nitrogen-proton dissociative charge exchange cross section. The poor agreement with experiment could apparently be much improved by the consideration of translational energy exchange. The proton excitation of the Schumann-Runge system is considered in the tracking approximation. The agreement with Green is better than would have been expected. A crude classical explanation of the temperature effect near threshold in nitrogen-electron ionizing collisions is suggested. (Author)
