hi all,

i have some questions to experts.

if i have cif file to any compound say ZnO and i fitted the exafs data with it.

Now the question is if i wish to fit the doped ZnO with the same cif and the same Enot then it shows large value of delta to fit. The question is have i look for different Enot or i have to change the cif for the doped one. Note i m talking about the main peak fit that only contain the Zn and O not the doped element. Is there any limit of delta for bond length? i think it should be small.

Thanks in advance
