RESONANT PHOTOEMISSION-STUDY OF SCF3 AT THE SC-2P AND F-1S ABSORPTIONEDGES - OBSERVATION OF THE SATELLITE STRUCTURE DUE TO THE STRONG HYBRIDIZATION EFFECT

The electronic structure of ScF3 has been investigated by resonant pho toemission at the Sc 2p and F 1s absorption edges. At off-resonant pho toemission, a charge-transfer-type satellite is found with an energy s eparation of about 13 eV below main peaks in valence-band and various core-energy regions. Another satellite is found with an energy separat ion of about 9-10 eV and its intensity is strongly enhanced at the exc itation energy of Sc 2p and F 1s thresholds. It is found to be the cha rge-transfer satellite that is caused by the strong hybridization effe ct between Sc 3d and F 2p states in the valence band.
