Hi Elsa: As Matt suggested, you want to change E0 in Athena to produce a new chi(k) spectrum. You can read the theoretical chi(k) spectrum that you made with E0=0 into Athena, adjust E0 for the measurement, and then plot in k the data and theory to see them match at low k. I encourage you to pok

Dear Matt,   I have to perform EXAFS analysis, and when I tried to fit the first shell, I found deltaE0 values of about 8 eV. Following the paper of Kelly et al (Analysis of soils and minerals using X-ray absorption spectroscopy. In Methods of soil analysis, Part 5: Mineralogical methods; 2008;
