Proton-rich Nuclei at and beyond the Proton Drip Line in the Relativistic Mean Field Theory
Ground state properties of proton-rich odd-Z nuclei in the region 55 ≤ Z ≤ 73 are studied in the relativistic mean field (RMF) theory. The RMF equations are solved by using the expansion method in the Harmonic-Oscillator basis. In the particle-particle channel, we use the state-dependent BCS method with a zero-range δ-force, which has been proved to be effective even for neutron-rich nuclei. Al...
متن کاملProton drip-line nuclei in Relativistic Hartree-Bogoliubov theory
Ground-state properties of spherical even-even nuclei 14 ≤ Z ≤ 28 and N = 18, 20, 22 are described in the framework of Relativistic Hartree Bogoliubov (RHB) theory. The model uses the NL3 effective interaction in the mean-field Lagrangian, and describes pairing correlations by the pairing part of the finite range Gogny interaction D1S. Binding energies, two-proton separation energies, and proto...
متن کاملRelativistic mean - field study of light nuclei near drip line
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 depe...
متن کاملLight 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...
متن کاملRelativistic mean-field description of nuclei at the drip-lines
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...
