摘要Photodissociation efficiency spectrum of anionic oxygen atom produced via ion-pair dissociations of carbon dioxide is recorded by means of the synchrotron radiation excitation (XUV photon energy 17.40-20.00eV). The present spectrum is assigned as the Rydberg-like excited ion-pair states, i.e., Tanaka-Ogawa and Henning series, ~C2∑g+ (CO2+) vibrational ground-state and excitation series. Three Rydberg series, npσu, npπu, and nfu, converging to ~C2∑g+ (0,0,0), show the higher cross sections.
