Kopsavilkums

The role of multiple-scattering contributions in the formation of the X-ray absorption fine structure (XAFS) above tungsten L edges is discussed for the non-stoichiometric tungsten oxides WO_3-x. It is found that the presence of linear or near-linear atomic chains in the WO_3-x crystal structure leads, due to the focusing effect, to a strong increase in the XAFS amplitude. which results in an admixture of the L₂-edge XAFS With the XAFS above the L₁ edge.
