Suppression of Multiple Scattering in Colloidal Model Systems — •Achim Lederer and Hans-Joachim Schoepe — Johannes Gutenberg-Universität Mainz, Institut für Physik, Staudinger Weg 7, 55099 Mainz, Deutschland

Light scattering is one of the most power full tools in soft matter physics to study the structure, kinetics and dynamics of the system of interest. Unfortunately the evaluation of conventional light scattering data is often complicated due to multiple scattering effects. In colloidal model systems multiple scattering can often be suppressed in particle form factor measurements by dilution or index matching methods, whereas it is a difficult task determining the structure factor. By a new designed Two Colour Dynamic Light Scattering setup, multiple scattering free dynamic and static light scattering data are obtained and compared to other multiple scattering free methods.
