Description	U-Au thin films with U concentration ranging from 0 to 100% have been prepared by sputter deposition and studied in situ by use of x-ray photoemission spectroscopy and ultraviolet spectroscopy. The valence band displays a two-peak structure near the Fermi level (EF). The peak right at EF (peak α) is characteristic of itinerant 5f states, the peak at approximately 0.7 eV indicates localized 5f states. The presence of the peak α at all compositions shows that 5f states are never purely localized. Relativistic electronic structure theory based on the local density approximation plus exact diagonalization of a multiorbital Anderson impurity model explains well the valence photoemission features. The essential role of hybridization in the U-based systems is emphasized.
