Abstract: (Elsevier)

We introduce for the first time the effective finite-range interaction of Gogny in the semi-classical description of heavy-ion reactions based on the Landau-Vlasov equation. The characteristics of the flow for heavy-ion collisions are studied as functions on the incident energy, the impact parameter and the mass number. The Gogny force reproduces the energy dependence of the real optical potential up to 200 MeV; we show that this energy dependence increases the flow and reproduces the values obtained with stiff local Skyrme forces. These results demonstrate the need of a proper account of the momentum dependence of the nuclear force, to extract informations on the nuclear equation of state, from high-energy heavy-ion collisions.
