The electron--electron coincidence technique has been used to measure the spectrum of autoionizing (Auger) electrons that are emitted following excitation of a core electron in O{sub 2} to the half-filled 1{pi}{sub {ital g}} orbital. The spectrum is dominated by transitions to doublet states, with very little intensity in quartet peaks. The kinetic energy spectrum calculated with inclusion of the effects of vibrational overlap in excitation and deexcitation as well as the effects of lifetime-vibrational interference agrees well with experiment. Comparison of the spectrum with the normal Auger spectrum shows significant similarities between the major features of each.
