In realistic growth processes, both kinetic and chemical factors determine the structure of the aggregates. Here, a model is proposed which interpolates between a purely diffusive and a purely chemical situation. There is crossover from a new, chemically limited growth model, with fractal exponents D = 1.55 ± 0.05 (2.00 ± 0.08) in two (three) dimensions, to diffusive cluster aggregation.Dans des processus réalistes de croissance, les facteurs cinétiques et chimiques déterminent la structure des agrégats. Nous proposons un modèle qui tient compte de ces deux facteurs. Nous déterminons l'exposant fractal de l'agrégation chimique D = 1,55 ± 0,05 (D = 2,00 ± 0,08) en deux (trois) dimensions. On étudie le comportement de crossover entre les régi...
