(ATOMKI), Debrecen, POB 51, H-4001, Hungary $ Department of Physical Sciences, University of Oulu, FIN-90570 Oulu, Finland 1 MeV proton excited carbon and oxygen K-LL Auger spectra from carbon dioxide were measured with a high resolution electron spectrometer (ESA-21) in the angular range from 0o to 180o. The transition energies, the linewidth and relative intensities were determined and compared with the existing theoretical and experimental data.
