The beams of (CO2)n cluster ions (n = 2-18) are studied by the adiabatic nozzle expansion of CO2 and subsequent ionization by the electron impact. They are analysed in a double focussed sector field mass spectrometer. In the case of 70 eV electron energy four homologous series of ions can be identified in the mass spectrum.
