Anion and cation formation following core-level photoexcitation of CO2
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 weak production 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-partialyield spectra at the O K edge reveal several previously unobserved electronic states. In addition, several cations such as CO2+ and O+2 were observed for the ﬁrst time.
