Abstract

High-resolution threshold electron spectroscopy has been applied to CO in the photon energy region 26-40 eV, where many sharp and broad CO⁺ states are observed. Dissociation of CO⁺ states in the photon energy range 30-40 eV has been investigated by threshold photoelectron-ion coincidence spectroscopy. Fragmentation characteristics of several distinct CO⁺ states, which are interpreted as Rydberg states converging to CO²⁺ states, are found to be state-specific, and are not the same as those of the underlying broad bands corresponding to valence excited CO⁺ states.
