Dynamics of the Reaction of N2+ with H2, D2, and HD

Product‐velocity‐vector distributions have been determined for the reactive and inelastic scattering of N2+ by H2, D2, and HD. These distributions show that the reaction proceeds by a direct short‐lived interaction rather than by a long‐lived collision complex. Most products are scattered in the original direction of the N2+ projectile at a speed somewhat greater than calculated from the ideal stripping model. The internal excitation of N2D+ and N2H+ is very high and decreases somewhat with increasing scattering angle. For HD there is an isotope effect that favors N2H+ by large factors at small scattering angles, and N2D+ by smaller factors at large angles. The N2+ scattered from D2 shows very little elastic component, but does reveal an inelastic process which is probably the collisional dissociation of D2.

Charge Transfer between Positive Alkali Ions and Atoms

The total cross sections for resonant charge exchange have been measured as a function of energy in the range from 10 to 500 eV for the Cs+–Cs, Rb+–Rb, and K+–K systems. The agreement with certain data obtained at higher energies for these systems and with theoretical cross sections of Smirnov is satisfactory.
