Abstract / Description:By use of high-resolution photoelectron spectroscopy we investigate the 4f spectral function of the heavy fermion compound CeRu2Si2 in the energy range close to the Fermi level. A normalization method proposed by Greber et al. (Phys. Rev. Lett. 79 (22) (1997) 4465) allows to resolve the Kondo resonance and its crystal field satellites. We discuss the applicability of this method with respect to a quantitative analysis of the data, and compare our experimental results to non-crossing approximation (NCA) calculations in the frame of the single impurity Andersson model (SIAM).
