Cross Sections for the Production of CO2+[A 2Πu, B 2Σu+→ X 2Πg] Fluorescence by Vacuum Ultraviolet Radiation

Fluorescence cross sections for the production of the CO2+[A 2Πu, B 2Σu+→ X 2Πg] bands are presented at several vacuum ultraviolet (vuv) wavelengths between 462 and 715 Å. The cross sections, for incident vuv photons from 600 to 680 Å, are 19 Mb for the production of CO2+ (A 2Πu) and 7 Mb for CO2+(B 2Σu+) and decrease monotonically toward the shorter wavelength region. The relative fluorescence cross sections of the observed sequences are also given for the various incident photon energies.
