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 L3-edge in ReO3 and Co K-edge in LaCoO3. We propose a modified wavelet transform procedure, which allows better discrimination of the overlapped contributions into the EXAFS signal.
