- W79069218 abstract "The pair distribution function (PDF) that can be obtained by Fourier transformation of powder diffraction data, traditionally was used to describe short range correlations in atomic positions. Amplitudes of peaks in experimental PDF decay as distance increases. Thus it was always assumed that PDF at large distances is featureless. Puzzled by the observation that PDF calculated for crystalline materials does not decay at large distances, if instrumental resolution is ignored, we studied the behavior of PDF at large distances. To the best of our knowledge, the origin of the PDF decay at large distances was never carefully discussed. It turns out, surprisingly, that increase in the number of neighbors at large distances does not lead to the decay of PDF independently from the type of the material. In other words PDF calculated with respect to one atom does not decay at large distances not only for the crystalline, but also for amorphous materials. We found that this behavior in amorphous materials is caused by random fluctuations in the radial number density. Thus PDF in amorphous materials decays mostly due to ensemble averaging over different central atoms. We achieve accurate quantative description of fluctuations for the case when atoms distributed randomly in space. Differences with amorphous case are discussed. The case of perfect single component crystals is the most interesting because in it all atomic positions are equivalent and there is no need to perform averaging over different atoms. Thus total measurable PDF for perfect crystals does not decay at large distances if instrumental resolution is ignored. However the origin of this behavior in crystals is significantly more complicated and this behavior of PDF is related to the still unsolved circle problem that C. Gauss formulated more than hundred years ago and that gave rise to the whole area in mathematics called lattice point theory. Further investigation of this case is obviously needed. For generality we discuss the case of PDF in d-dimensional space. Our results can be used to measure the amount of dislocations in crystalline materials and to test instrumental resolution in scattering experiments." @default.
