Abstract
The energetic proton emission has been investigated as a function of the reaction centrality for the system 58Ni _s16 58Ni at 30A MeV. Extremely energetic protons (EpNN > 130 MeV) were measured and their multiplicity is found to increase almost quadratically with the number of participant nucleons thus indicating the onset of a mechanism beyond one and two-body dynamics.
