Thank you Dr. Segre, So I should not be skeptical if my fitting results return a high Debye Waller value for my first shell as compared with the second shell. I appreciate your help. Hashem Stietiya On Fri, Oct 2, 2009 at 12:00 PM, wrote:

Dear All,

Does the Debye Waller value for the first shell have to be smaller than that of the second shell? can you have a situation where the Debye Waller value for the Zn-O first shell is 0.011 and for the Zn-Fe second shell is 0.003? so if there is thermal or static disorder in the first coordination shell,that must be the case for the second coordination shell?

Best Regards,
