Semi-classical kinetic approaches of heavy-ion dynamics

A semi-classical kinetic equation for the study of transport phenomena in nuclei is presented; it allows the analysis of the balance between mean field and individual collisions in heavy reactions at intermediate energies. The role of collisions in the onset of various regimes of reactions is discussed. The semi-classical equation gives insights on the microscopic mechanisms of energy equilibration. Strong limitations to the excitation energy available for particle evaporation are predicted in agreement with observed trends. The role of compression modes is underlined in particular with regard to nuclear multifragmentation. (orig.)
