    "abstract": "In this article we investigate the structure of the non-local part of the\nsymmetry term, that leads to a splitting of the effective masses of protons and\nneutrons in asymmetric matter. Based on microscopic transport simulations we\nsuggest some rather sensitive observables in collisions of neutron-rich\n(unstable) ions at intermediate ($RIA$) energies. In particular we focus the\nattention on pre-equilibrium nucleon emissions. We discuss interesting\ncorrelations between the N/Z content of the fast emitted particles and their\nrapidity or transverse momentum, that show a nice dependence on the\nprescription used for the effective mass splitting.",
