(96 MeV) 16O+58Ni and (133 MeV) 16O+48Ti reactions have been experimentally investigated by using coincident charged particle techniques. A closed-form theoretical approach, describing in a single picture the nonequilibrium component and the evaporation component of the angular correlation between particles and reaction residues emitted in a peripheral heavy-ion collision, is applied - in the hypothesis of sequential process - to the C-α, N-α, and O-α differential multiplicities for the 16O+58Ni at 6 MeV/nucleon and 16O+48Ti at 8.3 MeV/nucleon deep inelastic collisions. From this analysis some reaction mechanism information is deduced.
