[en] The photoion-photoelectron spectrum of O+, CO+ and CO2+ has been investigated under high resolution conditions. The O+ ion production is found not to be restricted to the CO2+ (C2Sigma+/g,0,0,0) predissociation. The (0,1,0) and (1,0,0) levels are clearly shown to be involved. The CO+ ion production involves all the vibrational states reached in the Franck-Condon region, i.e. up to (2,0,1) at 19.94 eV. The CO2+ molecular ion does not survive the predissociation in the entire range covered in the present work.
