摘要：
We present and discuss the bremsstrahlung isochromat spectra (BIS) of four d0 transition-metal oxides, namely ZrO2, HfO2, Nb2O5, and Ta2O5. The spectra are related to the density of unoccupied states in the conduction band. They give directly the magnitude of the crystal-field splitting and the dispersion of the metal-d bands. The trends observed in the spectra are discussed and compared to those found in the O 1s x-ray absorption spectra (XAS) of the same materials.
