Modelling of Scattering Diagrams — •Adrian Maier, Klaus Nusser, Gerald Johannes Schneider, and Dietmar Göritz — Universität Regensburg, 93040 Regensburg

Scattering methods are most suitable for studying the structure of unknown systems. Especially colloidal objects are of interest for both fundamental and applied science. Therefore an enormous amount of work has been done to extract structure information of such systems out of scattering diagrams. In particular the correlation between the structure of colloidal systems and the scattering diagrams is not fully understood yet. To gain more insight into this topic we numerically calculated scattering diagrams of simple colloidal objects.

In general experimental samples exhibit a significant polydispersity. In models, however, one usually assumes monodisperse particles. Consequently, we investigated the influence of a polydisperse distribution of diameters on scattering diagrams to determine the validity of the analysis.
