Abstract: For the first time, the reflection of SnO 2 is measured in a wide range of energies (from 4 eV to 28 eV) and the spectrum obtained is compared with the band structure that was previously computed with the help of the Kohn-Korringa-Rostoker (KKR) method. For energies that do not exceed the energy gap (E g approximately=3.8 eV) by more than 5 eV, the singularities of the spectrum are attributed to interband transitions in good agreement with the theoretical band-structure model. Beyond 10 eV, the interpolation is much more difficult because of the lack of accuracy of the method and the multiplicity of energy levels. It is concluded that the results obtained with the help of the KKR method are reliable if the computation is not extended to a wide range of energies.
