Polarized K‐emission and absorption spectra of the layered compounds GaS x Se 1− x ( x = 0, 0.6, 1) are measured in the range of about 10 eV below and above the gap. The polarization dependence of the spectra enables the investigation of the local p‐like DOS additionally resolved with respect to the m ‐quantum number symmetry. By alignment of the energy scales using XPS core‐orbital energies the experimental spectra can be compared with calculated local partial ( l, m ‐resolved) DOS after Robertson. The spectra are discussed with regard to the calculated DOS and to the structure of the compounds. The polarization dependence of the gap between the Ga K‐emission and absorption spectra shows the anisotropic character of chemical binding.
