    "abstract": "The isospin splitting of the nucleon mean field is derived from the Brueckner\ntheory extended to asymmetric nuclear matter. The Argonne V18 has been adopted\nas bare interaction in combination with a microscopic three body force. The\nisospin splitting of the effective mass is determined from the\nBrueckner-Hartree-Fock self-energy: It is linear acording to the Lane ansatz\nand such that $m^*_n \u003e m^*_p$ for neutron-rich matter. The symmetry potential\nis also determined and a comparison is made with the predictions of the\nDirac-Brueckner approach and the phenomenological interactions. The theoretical\npredictions are also compared with the empirical parametrizations of neutron\nand proton optical-model potentials based on the experimental nucleon-nucleus\nscattering and the phenomenological ones adopted in transport-model simulations\nof heavy-ion collisions. The direct contribution of the rearrangement term due\nto three-body forces to the single particle potential and symmetry potential is\ndiscussed.",
