Dynamical effects of momentum dependence of the nuclear mean field

We suggest several ways to study dynamical effects of the momentum dependen ce of the nuclear mean field in medium energy heavy-ion collisions, from in complete fusion to multifragmentation events. We present dynamical simulati ons based on a new transport code with a quite general form of mean-field n on-locality and we compare with local effective forces giving the same equi librium properties. We clearly see observable effects on the onset of insta bilities, on rates and angular distributions of pre-equilibrium particle em issions and on rapidity distributions of vaporization events for central co llisions at intermediate energies.
