Résumé : We apply a dynamical model which includes both dissipation and statistical fluctuations to the computation of triple differential cross sections for deep inelastic reactions. It is seen that for different Z values the overall pattern of the cross section d3σ/dθdEdZ (calculated, for the 280 MeV40Ar +58Ni system) as a function of E and θ is fairly well reproduced-the mean angular momentum transfer for the 365 MeV63Cu+197Au system is calculated and compared with γ-multiplicity measurements. In both applications, possible implications of the remaining discrepancies are discussed. © 1978 Springer-Verlag.
