Ionndash;Molecule Reactions of Cplus;with N2and O2

摘要

Using a tandem mass spectrometer, the reactionsCplus;plus;X2rarr;X2plus;plus;Crarr;Xplus;Xplus;plus;Crarr;CXplus;plus;C,where X is either nitrogen or oxygen, were studied in the ion energy range 5ndash;200 eV. By studying the attenuation of the Cplus;ion beam as a function of N2pressure at various electron energies, and by measuring the ionndash;molecule reaction cross sections at different electron energies, it was possible to estimate the contribution of the2Pand4Pstates of Cplus;to the reactions.
