The splice method in the EXAFS analysis, which was recently proposed f
or the direct determination of a radial distribution function (RDF), w
as applied to the systems with large disorder. The 4th-order cumulant
expansion method cannot reproduce a strongly asymmetric RDF, while the
splice method successfully gives the original RDF. Temperature depend
ence of the 1st nearest neighbor Br-Cu RDF in CuBr was investigated by
analyzing the Br K-edge EXAFS with the splice method.
