Abstract:
The finite energy resolution of EXAFS spectrometer is an important effect on EXAFS measurement. It lowers the EXAFS amplitude and the decrement in smaller k is greater than that in larger k. That causes smaller coordination number and the relative mean square displacement obtained from EXAFS data. This paper proposes a method to calculate the effect of the resolution on the structural parameters extracted from EXAFS. Structural parameters of Ge and Ni, as examples, were measured and calculated with different resolutions and the results are consistent with each other. The manner of how the effect occurs is discussed and a method to correct the influence of the finite energy resolution is presented.
