Figure 8
Screenshot of a Mathematica script for determining the effect of the isotropic DW factor on peak intensity and of TDS on the background of the powder pattern of spherical f.c.c. copper nanoparticles. The TDS [equation (25)[link]] is the `Debye TDS', which is a TDS model for Einstein oscillators. The powder pattern is calculated with the common volume function [equation (57)[link]] for a fully (linearly) polarized beam and corrected by the Lorentz factor [equation (30)[link]] and an isotropic Debye–Waller factor [equation (9)[link]]. A term to account for small-angle X-ray scattering (SAXS) is applied. A description of these terms is found later in the text.
