Sažetak
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, and yet simple and economical description of the nuclear many-body problem. By adjusting just a few model parameters: coupling constants and effective masses to global properties of simple spherical nuclei, it has been possible to describe many nuclear structure phenomena, not only in nuclei along the valley of $\beta$-stability, but also in exotic nuclei with extreme isospin values and close to the particle drip lines. The relativistic Hartree-Bogoliubov model has been applied in studies of structure phenomena that include: the strong isospin dependence of the effective spin-orbit interaction and the resulting modification of surface properties, the suppression of the spherical $N=28$ shell gap for neutron-rich nuclei and the related phenomenon of deformation and shape coexistence, the structure of the proton drip line nuclei in the region $31\leq Z \leq 73$, and ground-state proton radioactivity in nuclei $53 \leq Z \leq 73$. The model has also been used to calculate parity violating elastic electron scattering on neutron-rich nuclei, and neutron density distributions for atomic parity nonconservation experiments. The relativistic random phase approximation, based on effective mean-field Lagrangians with nonlinear meson self-interaction terms, has been used in the analysis of the dynamics of isoscalar dipole modes and of the structure of pygmy resonances.
