In this range, the sample must not be described at an atomistic level; one rather uses a continuum description in terms of an electron density or a … See more In X-ray or neutron small-angle scattering (SAS), Porod's law, discovered by Günther Porod, describes the asymptote of the scattering intensity I(q) for large scattering wavenumbers q. See more Since the advent of fractal mathematics it has become clear that Porod's law requires adaptation for rough interfaces because the value of … See more If the interface is flat, then Porod's law predicts the scattering intensity $${\displaystyle I(q)\sim Sq^{-4}}$$ where S is the surface area of the particles, which can … See more as Form factor asymptote For a specific model system, e.g. a dispersion of uncorrelated spherical particles, one can derive Porod's law by computing the scattering function S(q) exactly, averaging over slightly different particle radii, and … See more
