The pairing interaction in asymmetric nuclear matter — •Urnaa Badarch and Horst Lenske — Institut für Theoretische Physik, Universität Giessen

The pairing interaction and the density dependence of the nuclear matter symmetry energy are very important for understanding many phenomena in both nuclear physics and especially for the impact on exotic nuclei and astrophysics. We study the effects of the pairing on the symmetry energy and incompressibility using the relativistic density dependent hadron field theory (DDRH). Contributions from polarization self-energies are discussed. The results of our calculation for the isospin dependence of: (i) the effective pairing interaction (ii) nuclear symmetry energy (iii) incompressibility which are calculated within the mean field approximation in the range from symmetric nuclear matter to pure neutron matter will be presented.
