摘要
The role of the focusing effect in the formation of X-ray absorption fine structure (XAFS) is considered for ReO3, non-stoichiometric tungsten oxides WO3-x, and FeF3 having the perovskite-type structure. Two cases are mainly discussed: (1) an admixture of rhenium and tungsten L(2)-edge XAFS in ReO3 and WO3-x crystals to the one above rhenium and tungsten L(1)-edge and (2) high-order superfocusing effect in Fe-0-F-1-Fe-2-F-3-Fe-4 atomic chain in iron K-edge XAFS of FeF3 which is analysed using an ab initio multiple-scattering approach.
