Hard gammas and energetic protons as probes of nuclear dynamics

The reaction dynamics has been investigated in the 58Ni+58Ni at 30 MeV/u reaction studying energetic proton emission and heavy residue features. Moreover, measuring the hard gamma multiplicity associated to different classes of heavy residues we achieve a quantitative measurement of the reaction centrality. Experimental data have been also compared with dynamical calculations. Protons with energy exceeding more than five times the incident energy per nucleon were measured and their impact parameter dependence seems to indicate the presence of cooperative processes.
