Incompressibility of finite fermionic systems: Stable and exotic atomic nuclei

Exotic modes of excitation in atomic nuclei far from stability

We review recent studies of the evolution of collective excitations in atomic nuclei far from the valley of β-stability. Collective degrees of freedom govern essential aspects of nuclear structure, and for several decades the study of collective modes such as rotations and vibrations has played a vital role in our understanding of complex properties of nuclei. The multipole response of unstable...

Relativistic Description of Exotic Collective Excitation Phenomena in Atomic Nuclei

The low-lying dipole and quadrupole states in neutron rich nuclei, are studied within the fully self-consistent relativistic quasiparticle random-phase approximation (RQRPA), formulated in the canonical basis of the Relativistic Hartree-Bogoliubov model (RHB), which is extended to include the density dependent interactions. In heavier nuclei, the low-lying E1 excited state is identified as a py...

Analytically solvable mean - field potential for stable and exotic nuclei

Slater determinants built from the single-particle wave functions of the analytically solvable Ginocchio potential are used to approximate the self-consistent Hartree-Fock solutions for the ground states of nuclei. The results indicate that the Ginocchio potential provides a good parametrization of the nuclear mean field for a wide range of nuclei, including those at the limit of particle stabi...

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.
