چکیده
The structure of nuclei far off β-stability is investigated by nuclear many-body theory. In-medium interactions for asymmetric nuclear matter are obtained by (Dirac-) Brueckner theory thus establishing the link of nuclear forces to free space interactions. HFB and RPA theory is used to describe ground and excited states of nuclei from light to heavy masses. In extreme dripline systems pairing and core polarization are found to be most important for the binding, especially of halo nuclei. The calculations show that far off stability mean-field dynamics is gradually replaced by dynamical correlations, giving rise to the dissolution of shell structures.

Based on the systematic investigation of the data available for A ≥ 40, a Z 1/3 dependence for the nuclear charge radii is shown to be superior to the generally accepted A 1/3 law. A delicate scattering of data around R c /Z 1/3 is infered as owing to the isospin effect and a linear dependence of R c /Z 1/3 on N/Z (or (N − Z)/2) is found. This inference is well supported by the microscopic Rela...
