High Resolution PES Investigations on the Prototype Heavy Fermion Compound CeCu6

D. Ehm, F. Reinert, J. Kroha, O. Stockert, S. Huefner

We present high resolution photoemission investigations on the heavy fermion compound CeCu6. By application of a normalization procedure we can resolve the Kondo resonance and its crystal field structures in both the He II\alpha and He I\alpha data. A comparison with NCA calculations allows a quantitative determination of the Kondo temperature and the crystal field energies.
