Relativistic Hartree theory for nuclei far from the stability line

We study nuclei far from the stability line using the relativistic Hartree theory. We calculate the properties of various elements of the Periodic Table up to the proton and neutron drip lines with several parameter sets. After comparing the numerical results, we discuss nuclear properties near the drip lines in detail for the parameter sets that include nonlinear terms in the sigma-meson Lagrangian.
