Abstract

The dissociative charge-transfer of CO2 with H2+ and He+ is an "internal energy resonant" process. The electron-transfer produces CO2+ ions in specified electronic states and the probability of forming these states varies with the translational energy of the reactant. Thus both the total cross-section for charge-transfer, and the relative abundances of the fragment ions show a considerable variation with reactant-ion translational energy. Fluorescence spectra of CO2+ have been obtained for reactant-ion translational energies of 2000-4500 eV. © 1977.
