ABSTRACT
Optical reflectivity and resonant photoemission measurements on CePd3 yield a 4f binding energy Ef between 0.7 and 1.0 eV and set an upper limit of 0.3 eV on a surface shift of Ef. The 4f halfwidth at half maximum δ is between 0.5 and 0.8 eV. The spin fluctuation energy Γ = 20 meV is successfully related to Ef and δ by the Kondo impurity Ansatz.
