Abstract

Resonant angle-resolved photoemission spectroscopy has been performed on a heavy fermion material CeRu2Si2 at the 4d-4f core threshold. The angle-resolved photoemission spectra display a sharp peak at EF which shows a remarkable intensity variation as a function of momentum, suggesting an energy dispersion of the Kondo resonance state above EF. On increasing temperature, the peak intensity is rapidly suppressed, while it persists up to a temperature much higher than the Kondo temperature.
