Density dependent hadron field theory with nuclear matter and finite nuclei. — •Urnaa Badarch and Horst Lenske — Institut für Theoretische Physik, Universität Giessen, Germany

We have studied nuclear interactions by the coupling of nucleons to meson fields using Relativistic field theory for infinite nuclear matter and finite nuclei. In this calculations we used density dependent meson-baryon coupling constants taken from Dirac-Brueckner self-energies and loop diagrams for describing the static polarization effect. Results for infinite symmetric and anti-symmetric nuclear matter are presented. The role of the isovector interactions is investigated and compared to conventional empirical RHF models.The extension of the approach beyond the ladder approximations is discussed. Results of loop calculations are presented.The global properties of newly determined coupling constants are investigated in applications to infinite asymmetric and symmetric nuclear matter and finite nuclei using Relativistic Mean Field theory with Tomas-Fermi approximation.
