Abstract
Aggregation kinetics and cluster-size distributions are studied with off-lattice, diffusion-limited cluster-cluster simulations. With increased cluster crowding (occurring at late times) as measured by the normalized free volume, , both the kinetics speeds up and the size distribution broadens. The exponents characterizing each, and , respectively, are found to be universal functions of . Moreover, the relation continues to hold up to (the ideal gel point), implying mean-field kinetics still applies despite the crowding.
