摘要：

It is generally observed that cross sections for exothermic ion-molecule reactions decrease with increasing ion kinetic energies indicating a negligible activation energy. An important exception to this behavior is exhibited by the exothermic reaction O++N2→>NO++N, the cross section of which goes through a maximum as a function of ion energies. A study of the pertinent potential-energy curves, taking into account the proper symmetry- and spin-allowed combinations of thereactants and products, shows the origin of the apparently anomalous behavior of this reaction.
