Summary
We suggest several ways to study dynamical effects of the momentum dependence of the nuclear mean field in medium energy heavy-ion collisions, from incomplete fusion to multifragmentation events. We present dynamical simulations based on a new transport code with a quite general form of mean-field non-locality and we compare with local effective forces giving the same equilibrium properties. We clearly see observable effects on the onset of instabilities, on rates and angular distributions of pre-equilibrium particle emissions and on rapidity distributions of vaporization events for central collisions at intermediate energies.
