Relativistic Hartree-Bogoliubov theory in coordinate space: finite element solution for a nuclear system with spherical symmetry
A C++ code for the solution of the relativistic Hartree-Bogoliubov theory in coordinatespace is presented. The theory describes a nucleus as a relativistic system of baryons andmesons. The RHB model is applied in the self-consistent mean-field approximation to thedescription of ground state properties of spherical nuclei. Finite range interactions areincluded to describe pai...
متن کاملRelativistic Hartree-Bogoliubov theory with finite range pairing forces in coordinate space: Neutron halo in light nuclei
The Relativistic Hartree Bogoliubov (RHB) model is applied in the self-consistent mean-field approximation to the description of the neutron halo in the mass region above the s-d shell. Pairing correlations and the coupling to particle continuum states are described by finite range twobody forces. Finite element methods are used in the coordinate space discretization of the coupled system of Di...
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 Hartree-Bogoliubov and RPA description of exotic nuclear structure
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...
متن کاملSpherical Relativistic Hartree theory in a Woods-Saxon basis
The Woods-Saxon basis has been suggested to replace the widely used harmonic oscillator basis for solving the relativistic mean field (RMF) theory in order to generalize it to study exotic nuclei. As examples, relativistic Hartree theory is solved for spherical nuclei in a Woods-Saxon basis obtained by solving either the Schrödinger equation or the Dirac equation (labelled as SRHSWS and SRHDWS,...
