Antiproton Interactions with Neutron-rich Nuclei — •Stefanie Lourenco and Horst Lenske — Institut für Theoretische Physik, Universität Giessen

One of the most exciting topics of modern physics is to study antimatter. In connection to the upcoming FAIR facility antiproton-nucleus interactions are of special interest.

We describe the elastic pA-interactions by a microscopic optical potential derived from realistic HFB-ground state densities and the Paris pN T-matrix. The emission of mesons produced in the in-medium pN annihilation processes are studied perturbatively. Final state meson-nucleus interactions are taken into account by an eikonal approach. Results for pA-scattering and meson reactions are presented for Ni-isotopes.
