Abstract
By using low-angle static light scattering we study the aggregation of dense colloidal solutions under diffusion limited (DLCA) and reaction limited cluster aggregation (RLCA) conditions. While it has been rece ntly shown that DLCA surprisingly leads to a semiordered state, we sho w here that any order is lost under RLCA conditions. While in the firs t case a scattering peak at finite wave vector q is observed, in the s econd the scattered peak always occurs at q = 0.
