| Abstract: | We report a photoelectron spectroscopic study of the valence bands of epitaxial Ce(1 1 1) films grown on W(1 1 0) at room temperature. The evolution of γ → α → γ like phase transition of Ce is observed with increasing Ce coverage and the valence-band structures of γ-like Ce film are determined. The 4f and 5d photoemission cross sections in the photon energy region from 20 eV to 130 eV are presented and discussed. A 5d-like surface state and a 6s band bottom are identified. |
