Abstract
The EXAFS amplitudes of concentrated samples measured in the fluoresce nce mode strongly depend on the detection geometry through the self-ab sorption effect. Knowing the stoichiometry of the sample, we can fully correct for the self-absorption effect using a simple theory and obta in the true EXAFS. The correction procedure presented here for the Oxy gen K-edge EXAFS of NiO is generally applicable and should be the firs t step in the quantitative analysis of fluorescence EXAFS data of conc entrated samples.
