Evidence for nuclear matter transparency in central heavy-ion reactions for light symmetric systems around the Fermi energy

Reaction mechanisms in central heavy-ion collisions around the Fermi energy are investigated within the Landau-Vlasov semiclassical transport model. It is shown that the reaction dynamics precludes the formation of a fusion nucleus: In head-on collisions, a transition from fusion process to binary mechanisms occurs. A pure nuclear transparency is underlined for light symmetric systems around the Fermi energy. For medium-heavy systems, the memory of the entrance channel still exists but, in addition, dynamical multifragment production is observed. These predictions are qualitatively consistent with recent experimental observations.
