Colloidal systems with a Yukawa interaction potential have been investigated by static and dynamic light scattering. By simultaneously measuring the dynamic and static properties of the colloidal systems we obtained the hydrodynamic function H (Q ) at different concentrations. Further the self-diffusion coefficient of highly ordered colloids was determined by tracer and FRAP measurements and compared with BD simulation and theoretical predictions.
