Does one create very hot nuclei in heavy-ion reactions below 100 MeV/u?

A meticulous analysis of emitted charged particles in heavy-ion reactions have been carried out in the framework of the dynamical semiclassical Landau-Vlasov approach for the Ar+Al collisions at 65 MeV/u. In accordance with most of the recent experimental results, the binary reaction mechanism is the main reaction feature. Contrary to the expectations that below 100 MeV/u a mechanism reminiscent of low energy deep-inelastic reaction could create two very excited sources (the primary quasiprojectile and quasitarget), the simulation shows that this reaction mechanism is closely connected to the participant-spectator picture. Due to an abundant dynamical (participant) emission mainly centered at midrapidity, the primary quasiprojectile and quasitarget can be identified as not very hot spectators
