Abstract
The use of the extended x-ray absorption fine structure (EXAFS) technique has expanded rapidly in recent years.1,2 EXAFS provides information about the local environment of the x-ray absorbing atom. In addition to the interatomic distances r, the mean square deviation, δ 2, of r and the number of atoms, N, at r can be extracted from an EXAFS spectrum. However, in order to extract N and δ 2 the amplitude of the EXAFS spectrum must be calibrated. This has been done using theoretical calculations3 or empirically using known materials as standards,4 but depends critically on the accuracy of transferability from sample to sample. It is the aim of this paper to assess experimentally the accuracy of amplitude transferability and to understand some of the factors that may cause variability.
