Cross sections for the production of fluorescence of CO₂⁺in the photoionization of CO₂by 58.4-nanometer radiation

Emission spectra between 288 and 458 nm from the photoionization of CO2 by 58.4-nm radiation have been obtained. The total cross sections for emission of the B 2Σu+ → X 2Πg and A 2Πg → X 2Πg systems of CO2+ are found to be 1.7 and 2.5×10−17 cm2, respectively. Relative cross sections are given for the production of emission in individual vibrational features of the A → X system. Previously unidentified bands in the CO2+ A-X transition are reported.
