The large interest for the double ionization of CO2 is mainly due to the importance of CO2 in several atmospheric phenomena of the Earth and of other planets. As an example, the role of the CO22+ dication and its dissociation in the atmosphere of Mars has been recently shown. We have studied the double photoionization of CO2, in the 34-50 eV photon energy range, by synchrotron radiation at Elettra-ARPES end station of the Gasphase beamline. The synchrotron light source, provides the possibility of a continuous energy selection of photons, keeping a high intensity of the signal. The experiment has been performed by detecting electron-ion and electron-ion-ion coincidences.

Abstract
The large interest for the double ionization of CO2 is mainly due to the importance of CO2 in several atmospheric phenomena of the Earth and of other planets. As an example, the role of the CO22+ dication and its dissociation in the atmosphere of Mars has been recently shown. We have studied the double photoionization of CO2, in the 34-50 eV photon energy range, by synchrotron radiation at Elettra-ARPES end station of the Gasphase beamline. The synchrotron light source, provides the possibility of a continuous energy selection of photons, keeping a high intensity of the signal.
