https://doi.org/10.1007/978-981-13-2300-3 coefficient at energies above the absorption edge displays a fine structure called EXAFS. Such fine structure may extend up to 1000 eV above the absorption edge and may have an amplitude of up to a few tenths (normally 1–20%) of the edge jump.

(Kronig, 1931) or a short-range order theory in terms of scattering by neighboring atoms (Kronig, 1932, Hartree, et al. 1934, Shiraiwa, et al. 1958) is more appropriate. A major source of the confusion was that quantitative comparison between theory and experiment was difficult if not impossible at the time.
