Abstract:
An energy shift of the f(2) feature is detected between inverse photoemission surface and bulk f Line shapes in Ce compounds. A comparison with analogous Lu compounds shows a systematic enhancement of the 4f surface shift in the case of Ce (up to 0.3 eV). This effect is interpreted as an extra `’hybridization shift” in good agreement with the results of an Anderson impurity Hamiltonian calculation. These findings show that the on-site f-f correlation energy does not increase at the surface indicating unchanged screening dynamics despite the reduced nearest-neighbors coordination.
