Abstract
The aggregation of dense colloidal solutions has been investigated by means of low-angle static light scattering. We show that the scattered pattern exhibits a finite-q-vector peak, whose intensity and position change with time. We find that the intensity distributions scale according to S(q/,t)=(tF(q/), in agreement with the scaling law for spinodal decomposition. While d=3 for spinodal decomposition, here scaling requires that d=, the fractal dimension of the clusters.
