The spectra are compared with the results of electronic structure calculations for the pure bulk materials in the cubic phase, based on the self-consistent scalar-relativistic linearized muffin-tin orbital (LMTO) method. Comparing the experimental and calculated spectra good agreement is found. Angle-resolved XPS experiments show distinct surface contributions to the recorded spectra, especially to the potassium peaks and in the valence band region. |
