Exotic structure and decay of medium mass nuclei near the drip lines

Abstract

Nuclei at or near the N=Z line are of particular interest as micro-laboratory for fundamental effects. The simulation of many astrophysical objects requires the knowledge of properties and decay rates of nuclei near the drip lines. The structure and dynamics of protonrich A≃70 nuclei and neutron-rich A≃100 nuclei are influenced by shape coexistence and mixing. A realistic description of shape coexistence phenomena requires beyond-mean-field approaches. Results concerning the self-consistent description of exotic phenomena including anomalies in mirror energy differences of proton-rich nuclei, triple shape coexistence in neutron-rich N=58 Sr and Zr isotopes as well as Gamow-Teller β-decay strength distributions, half-lives, andβ- delayed neutron emission probabilities of neutron-rich nuclei in the A≃100 mass region obtained in the frame of the complex Excited Vampir model using realistic effective interactions in large model spaces are presented.
