Abstract
Angle-resolved resonant electron spectra following vibrationally resolved C 1s nl ( = 0,1) excitations in CO have been measured. The observed groups of resonant Auger lines exhibit great similarity in shape to the C-KVV group of non-resonant Auger lines and the observed angular distribution behaviour reflects the symmetry-dependent anisotropies of the excitation process. The molecular progressions in the C 1s* resonant Auger spectrum could be clearly identified due to their different angular distribution behaviour. Furthermore, it could be shown that the screening energies for spectator electrons over binding energy have a linear dependence between 3p, 4p and threshold as was expected for the higher p-symmetry Rydberg orbitals.
