Abstract

X-ray absorption and glancing angle reflectivity measurements in the energy range of the Nitrogen K-edge and Gallium M2,3 edges are reported. Linear muffin-tin orbital band-structure and spectral function calculations are used to interpret the data. Polarization effects are evidenced for the N-K-edge spectra by comparing X-ray reflectivity in s- and p-polarized light.
