Résumé :

In a statistical theory based on semi-classical approximations, we show that the fast fission phenomena (FF) can appear as the natural link between the deep inelastic reactions (DIR) and the compound nucleus formation (CN), depending on the initial conditions of energy and mass asymmetry. The DIR deal essentially with the energy and the angular momentum dissipation, the FF with the mass asymmetry relaxation. By the analysis of the dynamical trajectories and of the mean values of the physical observables E, θ, Δl, ΔA, we show how to separate the ranges of l0 waves in the entrance channel which specifically contribute to each process. The calculations are performed for the systems Ar on Ho and Mg on Ta at several identical c.m. energies. © 1986.
