Abstract :
Using low-coherence dynamic light scattering (LCDLS) method, which allows us to measure the light single scattered from dense media, we investigated the hydrodynamic properties of particles. The effect of hydrodynamic interactions on diffusion of particles is studied by measuring the dependence of the diffusion coefficient on the particle concentration. The hydrodynamic radius distributions with an accuracy within 3% are obtained for dense suspensions with the volume fraction of 10 vol.% by using the CONTIN method.
