Abstract A model with two collective variables,r-the distance between nuclei andθ-the deflection angle in the center-of-mass system, was used. In the classical frame, the time evolution of the nuclear composite system confirmed the Wilczynski model. It was obtained that for the interacting system40Ar(300 MeV)+197Au, deep inelastic collisions correspond to 1-values in the range 126 ≦ 1 ≦ 210. This implies interaction times in the range 5×10−22 s to 3.4×10−21 s and energy losses from 30 to 160 MeV. The obtained 1cr value, 1cr=125 and the fusion cross section are in agreement with experimental data. Calculating the double differential cross sectiond 2σ/dθdE in the statistical formalism one obtains a qualitative agreement with experimental data. The introduction of statistical fluctuations in calculating the angular distributiondσ/dθ determines a good description of experimental data. The energy dissipation up to 130 MeV (deduced from Wilczynski plot) is in good agreement with experimental data.
