Scaling of energy deposition in central heavy ion reactions at intermediate energies

Semiclassical transport simulation of heavy-ion reactions (HIR) between about the Fermi energy and 100A MeV reveals a perfect linear correlation between the maximal excitation energy put into a nuclear system and the incident en- ergy. This scaling feature becomes a universal property of HIR independent of reaction entrance channel parameters (system size, asymmetry and energy) when these excitation maxima are expressed in units of the system available energy. The constancy of the excitation energy fraction in the system available energy is on the best corroborate by those analysis of experimental data which do not presume a reaction mechanism dominating the collision process.
