Abstract
The carbon K emission spectrum of gaseous CO2 has been recorded in high resolution using the grazing incidence technique. Vibrational fine structure corresponding to vibrational excitations in the 2 Pi u and 2 Sigma u+ final states is clearly resolved in the spectrum. From a Franck-Condon fit of harmonic oscillators the natural lifetime width of the C 1s state has been determined to be 0.07+or-0.02 eV.Keywords
