    Notes: Abstract. The relativistic Hartree-Bogoliubov (RHB) model is extended to include density-dependent meson-nucleon vertex functions. Compared with standard relativistic mean-field effective interactions with non-linear meson-exchange terms, the density-dependent meson-nucleon couplings provide an improved description of asymmetric nuclear matter, neutron matter and nuclei far from stability. The relativistic quasiparticle random-phase approximation (RQRPA) is formulated in the canonical single-nucleon basis of the relativistic Hartree-Bogoliubov (RHB) model. Both in the particle-hole and particle-particle channels, the same interactions are used in the RHB calculation of the ground state and in the matrix equations of the RQRPA. The RHB + RQRPA is employed in the analysis of multipole excitations of neutron-rich oxygen isotopes.

    Relativistic Hartree-Bogoliubov description of deformed light nuclei (2004)

    Notes: Abstract. The Relativistic Hartree-Bogoliubov model is applied in the analysis of ground-state properties of Be, B, C, N, F, Ne and Na isotopes. 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. Neutron separation energies, quadrupole deformations, nuclear matter radii, and differences in radii of proton and neutron distributions are compared with recent experimental data.
