    "abstract": "In a relativistic Brueckner-Hartree-Fock calculation we include explicit\nnegative-energy states in the two-body propagator. This is achieved by using\nthe Gross spectator-equation, modified by medium effects. Qualitatively our\nresults compare well with other RBHF calculations. In some details significant\ndifferences occur, e.g, our equation of state is stiffer and the momentum\ndependence of the self-energy components is stronger than found in a reference\ncalculation without intermediate negative energy states.",
