N2 - Kinetics of aggregation of surfactant monomers into micelles and micellar relaxation are controlled by two competing mechanisms. The first is the molecular or stepwise mechanism in which the change of the aggregate size occurs with capture or emission of single surfactant monomer. The second is the mechanism of fusion of two aggregates at collision and spontaneous fission of aggregates in fragments due to their internal instabilities. The first mechanism is described by the Becker-Döring kinetic equations for concentration of molecular aggregates with different aggregation numbers [1-5]. The second mechanism is described by the generalized Smoluchowski kinetic equation [6] which includes fragmentation terms as well as traditional coagulation terms. In fact, the generalized Smoluchowski kinetic equation describes joint action of the molecular and the fusion-fission mechanisms of surfactant aggregation and disaggregation. Although the basic kinetic schemes are now clear, there is a lack of direct expe
