Photoemission study of CeCu6

The energy distribution of the 4 f partial density of states in CeCu 6 has been observed by means of the resonant enhancement of the 4 f cross section associated with the excitation of the 4 d electron. The main 4 f line is located 2.3 eV below the Fermi edge. In addition to the main line, states with the 4 f character are distributed all over the valence band. The 3 p -3 d resonances of the Cu 3 d band and its satellite are also found.
