Abstract
We have investigated photodesorption from condensed carbon dioxide for photon energies ranging from 13 to 35 eV using synchrotron radiation. We report the desorption of O2+ ions at energies as low as 13 eV, and discuss this behaviour in terms of ion–molecule reactions. The desorbed CO+ ion yield shows resonances at ∼15.4 and ∼17 eV, below the gas-phase thermodynamic threshold for CO+ formation. These peaks are also assigned to a two-step process, in which the photodissociation of CO2 leads to neutral CO production.
