Kopsavilkums

The role of the focusing effect in the formation of X-ray absorption fine structure (XAFS) is considered for ReO₃, non-stoichiometric tungsten oxides WO_3-x and FeF₃ having the perovskite-type structure. Two cases are mainly discussed: (1) an admixture of rhenium and tungsten L₂-edge XAFS in ReO₃ and WO_3-x crystals to the one above rhenium and tungsten L₁-edge and (2) high-order superfocusing effect in Fe₀F₁Fe₂F₃Fe₄ atomic chain in iron K-edge XAFS of FeF₃ which is analysed using an ab initio multiple-scattering approach.
