Relativistic mean - field study of light nuclei near drip line
نویسندگان
چکیده
The relativistic mean field theory is applied to study some exotic properties of neutron rich nuclei as recently observed, namely, extension of the drip-line for F nuclei from 29 F to 31 F and the appearence of a new shell closure at neutron number N = 16. We find 31 F to be bound against one-neutron dripping but unbound only marginally for two neutron separation. The calculated functional dependence of one-neutron separation energy with neutron number for different values of T Z = (N − Z)/2 signals a new shell closure at N = 16 for neutron rich nuclei with T Z ≥ 3. This is further corroborated from the study of the deformation and the gap across the Fermi surface in these light nuclei.

Light Nuclei near Neutron and Proton Drip Lines in the Relativistic Mean-Field Theory
We have made a detailed study of the ground-state properties of nuclei in the light mass region with atomic numbers Z=10-22 in the framework of the relativistic mean-field (RMF) theory. The nonlinear σω model with scalar self-interaction has been employed. The RMF calculations have been performed in an axially deformed configuration using the force NL-SH. We have considered nuclei about the sta...

The Relativistic Hartree Bogoliubov theory is applied in the mean-field approximation to the description of properties of light nuclei with large neutron excess. Pairing correlations and the coupling to particle continuum states are described by finite range two-body forces. Using standard parameter sets for the mean-field Lagrangian and the pairing interaction of Gogny-type, self-consistent so...

We present a review of recent applications of the relativistic mean-field theory to the structure of nuclei close to the drip-lines. For systems with extreme isospin values, the relativistic Hartree-Bogoliubov model provides a unified and self-consistent description of mean-field and pairing correlations. The model has been applied in studies of structure phenomena that include: formation of ne...

A review of recent applications of the relativistic mean-field theory to the structure of exotic nuclei is presented. Models based on the relativistic mean-field approximation provide a microscopically consistent description of the nuclear many-body problem, not only in nuclei along the valley of β-stability, but also in exotic nuclei with extreme isospin values and close to the particle drip l...
