XANES SPECTROSCOPY USING HIGH-RESOLUTION RESONANT RAMAN-SCATTERING - APPLICATION TO HOLMIUM

The use of resonant Raman scattering at x-ray energies for studies of the near-edge structure of the absorption edge is presented. The potential of the method is shown in the case of the Ho L(III)-edge, which is measured using Cu K-alpha-1 radiation and a focusing crystal spectrometer. The results are interpreted within a model where the density of final electron states is constant plus a narrow band where the density is high (white line). A comparison with the other methods used in x-ray absorption near-edge structure spectroscopy is also given.
