EFFECTS OF GOGNY-TYPE INTERACTIONS ON THE NUCLEAR-FLOW

A flow analysis on symmetric and asymmetric reactions from 100 to 400 MeV/nucleon is performed in the framework of the semiclassical Landau- Vlasov approach. In this energy range our results present two differen t trends. At lower energies it is governed by the momentum dependence of the nuclear optical potential, whereas at higher energies its densi ty dependence plays a crucial role leading to a rather pronounced sens itivity to the incompressibility modulus. The nonlocality of the nucle ar interaction is relevant for asymmetric colliding systems. With an i ncompressibility modulus in the vicinity of 200 MeV, an excellent quan titative description of the flow behavior with incident energy and imp act parameter or the system mass is provided.
