Figure 7.

Azimuthally averaged scattering profiles of dilute silica and polystyrene colloidal suspensions recorded with the Eiger2 4M detector at a sample-to-detector distance of 31 m. The mean radii (R _s) of the particles are 300 nm (silica) and 1012 nm (PS) and the corresponding polydispersities in terms of the width of the Gaussian size distribution (σ _R ) are 5.4 and 4.0 nm, respectively. The model represents a polydisperse sphere scattering function, which can describe up to the 70th minimum as illustrated in the inset.
