Wavelet data analysis of EXAFS spectra

The application of wavelet transform to the analysis of the extended X-ray absorption fine structure (EXAFS) from perovskite-type compounds is presented on the example of the Re L(3)-edge in ReO(3) and Co K-edge in LaCoO(3). We propose a modified wavelet transform procedure, which allows better discrimination of the overlapped contributions into the EXAFS signal. (C) 2008 Elsevier B.V. All rights reserved.
