Exotic nuclei in a relativistic mean-field approach

Abstract
The neutron rich Zr isotopes are studied in a relativistic mean-field approach. A transition from spherical to strongly deformed shapes is obtained around A≃100 and ground state deformations are found, which are in size close to superdeformed shapes. Furthermore, very large radii are predicted in the vicinity of the neutron drip line due to the combined effects of deformation and neutron excess.
