摘要：

Optical reflectivity of the compound CeCu5 was investigated over a wide spectral range (1 meV-6 eV) at 5 and 300 K. Anomalous features were detected at low temperature, corresponding to a small plasma frequency (scaled with the Kondo temperature), and to the opening of a small gap of a few meV.
