Thanks for the quick response. As per the data collection range is concerned, we have limitation of 300eV above the edge.

I think I had done data processing in Athena right. I know that the peak at position less than 1 Angs can not be real but I am unable to remove it by data processing in Athena. As per the model is concerned I am attaching herewith feff calculation result and the XRD results for different bondlengths of the sample. By comparing them it seems that model is right.

On the other hand poor energy resolution is also one of the reasons for this kind of results. I had alraedy read about this Ei component earlier in papers, but I am unable to follow the procedure like how to calculate it using a known standard. From where I can get literature related to this? It will be really helpfull.

With regards
