  A new method for enhancing the production of the negatively charged helium dimer He2−

  摘要：

  The production of the negatively charged helium dimer He-2(-) can be enhanced by nearly an order of magnitude by utilizing laser excited alkali metals as charge-exchange material for fast He-2(+) ions. The enhancement can be attributed to both steps in the charge-exchange reactions converting He-2(+) via He-2 (a(3) Sigma(u)(+)) to He-2(-) ((4) Pi(g)).

  fraction of conversion from the B̃ to à state, was smaller than those in He(23S) Penning ionization and HeI photoionization. It was concluded that two types of charge-transfer processes occur in the thermal energy He2+ + CO2 reaction: (1) energy resonant process leading to CO2+ (C̄) and (2) non-energy resonant process leading to CO2+ (B̄, Ã). The CO2+ (Ã) vibrational distribution was found to shift to

  The flowing afterglow technique has been used to measure rate coefficients and product channels for the reactions of He2+, Ne2+, and Ar2+ with the rare-gas atoms Ne, Ar, and Kr, and with the molecules NO, O2, CO, N2, and CO2 at 200°K. These reactions are found to proceed principally by asymmetric charge transfer. The experimental results for the reactions of the rare-gas molecular ions with rare-gas atoms indicate a correlation between reaction probability and reaction exoergicity analogous to that observed for asymmetric atomic ion–atomic neutral charge-transfer reactions. The reactions with molecules are found to proceed with unit reaction probability with the exception of the reactions Ar2++O2 and Ar2++NO. The reaction probability for the reactions of the molecular rare-gas ions with molecules is not very sensitive to an energy resonance criterion. Finally, rate coefficients and reaction channels for the reaction of the mixed rare-gas molecular ions HeNe+, ArKr+, and ArCO+ with Ne, Kr, and CO, respectively, are reported.

  Ion-molecule reactions of the sort observed as secondary reactions in mass spectrometers have been treated by the methods of the modern kinetic theory; that is, the rate of reaction is expressed in terms of the velocity distribution functions of the reactants and the cross section for the reaction. The cross section, which is calculated by means of the properties of the classical collision orbits, is found to have an inverse square root dependence on energy. The ion distribution function, which is far from Maxwellian, is found by means of an explicit solution of the Boltzmann equation. A simple relation is given which relates the mass spectrometric data to the specific rate of the same reaction under thermal conditions. For the simpler molecules, this rate may be calculated completely a priori, with excellent agreement with experiment.
