Hi all, I am fitting CuO2 EXAFS data taken at SSRL using the Artemis. But there is a problem with fitting results that SO2 parameter is coming very low around 0.50. I had also taken CuO2 data from different data bases to check whether theere some problem with my data, but after fitting them, the same problem of low SO2 is coming. In some research papers given SO2 parameter for CuO2 equal to 0.82. But I am unable to get that why all the CuO2 data giving low value of SO2. Is there any other fitting procedure to fit the compounds like CuO2 ?????? With thanks Abhijeet Gaur
