SAS contribution from size, and size and shape dispersion of crystals. Reduced PDFs G(r ) of crystals with f.c.c. (unit cell 3.8907 Å) structure and negative shape function [ - \gamma (r )], which is the correction term in equation (6)[link], for (a) monodisperse powders of cubic crystals with size ranging from ∼5 to ∼143 nm, (b) monodisperse and polydisperse powders of cubic crystals, (c) monodisperse powders of cubic, hollow cubic and a 1:1 mixture of these crystals, and (d) monodisperse powders of hollow cubic crystals and polydisperse powders of hollow cubic crystals. The short-range pair distances are magnified in the inset. The particle sizes of the monodisperse powders were chosen as the mean of the polydisperse system and the size yielding the best match of the shape functions. The left-side insets in (a) and (b) magnify the short-range pair distances. The right-side inset of (b) shows the SAS particle shape contributions to the intensity profile.
