Abstract

Mass-resolved anion and cation partial-yield spectra following photoexcitation of CO₂ have been recorded in the vicinity of the C 1s and O 1s thresholds. Anion production was found to be site specific: a weakproduction of O^- was observed on the π* resonance near the C K edge, whereas both C^- and O^- fragments were observed near the O K edge. Due to suppression of the shape resonances that dominate the cross section above the core thresholds, the anion-partial-yield spectra at the O K edge reveal several previously unobserved electronic states. In addition, several cations such as CO²⁺ and O₂⁺ were observed for the first time.
