Abstract

The theoretical model, successfully employed to describe in a single picture the non-equilibrium component and the evaporation component of the angular correlation between particles and reaction residues emitted in a peripheral heavy-ion collision for various nuclear systems and in a wide energy range, is here revisited to keep into account the different dynamical dispersion in near-side and far-side trajectories. This new approach, applied to the C- differential multiplicities for the

¹⁶O$ + $⁵⁸Ni

at 6MeV/A and

¹⁶O$ + $⁴⁸Ti

at 8.3MeV/A deep inelastic collisions, allows to explain more in detail the reaction mechanism of such processes.
