摘要：

The electronic structure of Mott-Hubbard-type Ti and V oxides have been studied by photoemission and X-ray absorption spectroscopy. The evolution of the spectra across the Mott transition indicates characteristic transfer of spectral weight from the incoherent to the coherent part of the spectral function. Across the metal-insulator transitions induced by carrier doping, new spectral weight is shown to fill the band gaps of the parent compounds.
