The production of CO2+(B2 Sigma u+( nu '=0) to x2 Pi g) fluorescence radiation by extreme ultraviolet excitation of CO2 was experimentally investigated in the 650-685AA region using synchrotron radiation. The cross section for the production of fluorescence radiation was found to exhibit structural features corresponding to the Tanaka-Jursa-LeBlanc bands, indicating that the upper states associated with these bands interact with the CO2+(B2 Sigma u+)+e- continua, producing the ion in this excited state by autoionization.
