The discrepancy between photoionization mass spectrometry and photoelectron spectroscopy in the CO/sup +//O/sup +/ ratio from CO/sub 2/ at 584 A is resolved by new measurements. New features in the photoelectron spectrum of CO/sup 2 +/(C /sup 2/..sigma../sup +//sub g/) lead to a new vibrational analysis, with vibration frequencies close to those of CO/sub 2/(X/sup 1/ ..sigma../sup +//sub g/). The observations are discussed in terms of a perturbation of the C /sup 2/..sigma../sup +//sub g/ state by the ionization continuum of either the X /sup 2/Pi/sub g/ state or the /sup 4/Pi/sub u/ state of CO/sup 2 +/.
