Abstract

We study the 16O + 58Ni deep inelastic reaction by using coincident charged techniques. Inclusive as well as exclusive data of the C, N, and O fully-damped fragments and their associated light charged particles (p, d, t, and -particles) have been collected at the IReS Strasbourg VIVITRON Tandem facility. The velocity distributions of the emitted protons and the associated multiplicity polar plots are analyzed by means of a model which describes simultaneously the nonequilibrium and the evaporative (equilibrated) components of a deep inelastic reaction mechanism. Estimates on polarization phenom- ena as well as the associated "decay times" of the reaction have been obtained. The hypothesis of a new "fan effect" is proposed for the proton sequential emission in the deep inelastic scattering of 16O + 58Ni at 8.25 MeV/nucleon.
