Relativistic RPA Functions with Density Dependent NN Interactions — •Andreas Fedoseew and Horst Lenske — Institut für Theoretische Physik, Universität Giessen

We derive longitudinal and transverse response functions taking into account relativistic RPA correlations. For our calculations we use an effective Lagrangian characterized by density-dependent meson-nucleon vertex functionals. The explicit density dependence of the meson-nucleon couplings is obtained from ab-initio Dirac-Brueckner calculations, which lead to additional rearrangement terms in the residual two-body interaction. We present results for symmetric and antisymmetric nuclear matter and closed shell nuclei using local density approximation.
