High-resolution resonant photoemission study of the 4f states in a typical Kondo system: CePd3

We exploited resonant photoemission at the Ce 4d --> 4f absorption edge to investigate the Ce 4f states in CePd3. High resolution spectra reveal, near the Fermi level, the characteristic fine structure of intermediate valence Ce compounds. The spectral lineshape is consistent with the typical "Kondo" character of CePd, but the prominent (f(0)) ionization peak is found at the unusually low binding energy of 1 eV. We briefly discuss the implications of these observations.
