Abstract : The ionization of CO2 was investigated in a double mass spectrometer, and the breakdown graph was constructed. The appearance potential of O(+) formed in dissociative charge transfer is shown to be 22.4 eV, while the electron impact value is 19.5 eV. The discrepancy is explained according to Wigner-Witner correlation rules. A break in the electron impact ionization efficiency curve is explained as being due to charge exchange between CO(+) ions, formed in the dissociative charge transfer, and CO2. (Author)
