Hi all, I had posted a problem related to fitting results of Cu2O. But there are some problems related to the fitting procedure . So now I have used a different fitting procedure, still there are problems with fitting results. like 1. The value of SO2 is coming low. 2. Value of E0 is coming high though I have calibrated the experimental data. 3. The ss (Debye Waller factor) for some of the paths are coming very high. I am not able to understand the value of ss for multiple scattering path. One more problem is that if I try to align the data with theory by adjusting E0 , the data get distorted. The Artemis file is attached herewith. This time I had made fitted the whole data in one fit by taking all parameter as guessed. With thanks Abhijeet Gaur
