摘要：

HeI and Mg Kα1,2 valence band photoelectron spectra of polycrystalline samples of NbO2, MoO2 and RuO2 are reported. A marked increase is observed in the intensity of the metal 4d structure, relative to that due to oxygen 2p electrons, on changing from X-ray to UV excitation. The superior resolution of the 4d signals in the HeI spectra reveals the presence of the Fermi edge in the metallic oxides MoO2 and RuO2. In addition, the HeI spectrum of MoO2 shows a splitting of the metal 4d signal, confirming established ideas concerning the electronic structure of such materials. © 1979.
