Abstract

Angle-resolved high-resolution photoelectron spectra of CO C 1s satellite lines were taken at a photon energy of 330 eV. The observed angular distributions assist in identifying the correlation effects which lead to the formation of different satellite lines, confirming recent theoretical and experimental results on this topic. Four conjugate shake-up satellite lines with beta =0 were observed, leading to a strongly aligned core-excited state in the molecular ion. These states decay anisotropically via participator Auger transitions, which carry along the angular momentum of the ionized core to double-hole final states. We present the first clear identification of the initial states of these recently observed K-shell satellite Auger transitions with pronounced decay anisotropy.
