Since hypernuclei are unique laboratories for investigations of the interaction between hyperons and nucleons and even among hyperons a unified description of baryonic inmedium interactions is an important requirement. Unfortunately the application of DiracBrueckner theory to medium and high mass nuclei is technically not feasible. A rather satisfactory approach providing a practicable way to u...

Nuclear many-body theory is used to study nuclear matter and finite nuclei at extreme isospin. In-medium interactions in asymmetric nuclear matter are obtained from (Dirac-) Brueckner theory. Neutron skin formation in Ni and Sn isotopes is investigated by relativistic mean-field calculations in DDRH theory with density dependent meson-nucleon vertices. Applications to light nuclei are discussed...
