“…The AXD approach to partial structure factor determination was originally suggested by Krogh-Moe (1966), and the idea was developed and extended to anomalous neutron diffraction by Ramaseshan (1971a, 1971b). Bondot (1974) used x-ray wavelengths from two tube sources (Cu K α and Ag K α ), combined with a neutron diffractogram, in an effort to derive the partial pair-correlation functions of amorphous GeO 2 .…”

The techniques of neutron diffraction and x-ray diffraction, as applied to structural studies of liquids and glasses, are reviewed. Emphasis is placed on the explanation and discussion of the experimental techniques and data analysis methods, as illustrated by the results of representative experiments. The disordered, isotropic nature of the structure of liquids and glasses leads to special considerations and certain difficulties when neutron and x-ray diffraction techniques are applied, especially when used in combination on the same system. Recent progress in experimental technique, as well as in data analysis and computer simulation, has motivated the writing of this review.

“…The anomalous dispersion technique was first suggested for amorphous materials by Krogh-Moe [15] and is employed successfully with x-rays at synchrotron radiation sources, which provide the necessary required incident intensity and sufficiently dynamic energy spectrum that encompasses the required absorption edge as well as an energy void of all resonant effects. The equivalent neutron technique involves the variation in the neutron scattering length with wavelength around an absorption resonance,…”

“…The anomalous dispersion technique (Krogh-Moe, 1966;Warburton et al, 1987) is based on the fact that near an absorption edge the X-ray form factor has both real and imaginary parts which are wavelength dependent f(Q) = fO(Q) + M' (A) + iM"(",) (VIII. 10) The utilisation of anomalous dispersion to separate component correlation functions has, however, only really become feasible with the advent of suitable diffractometers on synchrotron X-ray sourees, which allow the wavelength to be continuously varied to obtain the optimum values of M' (",) and M"(A).…”
