High-energy band structure of gold

The band structure of gold for energies far above the Fermi level has been calculated using the relativistic augmented-plane-wave method. The calculated $f$-band edge (${\Gamma }_6^{-}$) lies 15.6 eV above the Fermi level is agreement with recent photoemission work. The band model is applied to interpret temperature-modulated reflectance data covering photon energies up to 35 eV.
