Abstract
The C 1s photoelectron spectrum of CO has been measured with high reso lution in the threshold region. The data exhibit hitherto unresolved v ibrational structure on the C 1s main photoelectron line as well as ne w features in the satellite region. The vibrational energy of the COion is 301 +/- 3 meV. The vibrational structure changes dramatically w ith photon energy due to the influence of the sigma shape resonance. The new satellite lines which are not present at high photon energies are attributed to conjugate shakeup processes.
