Single particle versus collectivity, shapes of exotic nuclei

Particle-vibration coupling and shell structure of exotic nuclei

We discuss the effects of particle-vibration coupling on the shell structure of nuclei near the neutron drip line by choosing, as examples, 10Be and 24O cores. In particular, we calculate the energy shifts of single-particle neutron states induced by the interaction with collective modes. In the case of the 10Be core, the coupling to 2+ states is responsible, within our model, of narrowing the ...

Exotic Atoms and Exotic Nuclei

Fission Barriers of Exotic Nuclei

Using available experimental data on fission barriers and ground-state masses a detailed study on the predictions of different models concerning the isospin dependence of saddle-point masses is performed.

Reaction Dynamics with Exotic Nuclei

We review the new possibilities offered by the reaction dynamics of asymmetric heavy ion collisions, using stable and unstable beams. We show that it represents a rather unique tool to probe regions of highly Asymmetric Nuclear Matter (ANM) in compressed as well as dilute phases, and to test the in-medium isovector interaction for high momentum nucleons. The focus is on a detailed study of the ...

Microscopic models for exotic nuclei

Starting from successful self-consistent mean-field models, this paper discusses why and how to go beyond the mean field approximation. To include long-range correlations from fluctuations in collective degrees of freedom, one has to consider symmetry restoration and configuration mixing, which give access to ground-state correlations and spectroscopy. PACS. 21.60.-n Nuclear structure models an...
