Pairing properties in relativistic mean field models obtained from effective field theory

We apply recently developed effective field theory nuclear models in mean field approximation ~parameter sets G1 and G2 ! to describe ground-state properties of nuclei from the valley of b stability up to the drip lines. For faster calculations of open-shell nuclei we employ a modified BCS approach which takes into account quasibound levels owing to their centrifugal barrier, with a constant pairing strength. We test this simple prescription by comparing with available Hartree-plus-Bogoliubov results. Using the new effective parameter sets we then compute separation energies, density distributions, and spin-orbit potentials in isotopic ~is t nic! chains of nuclei with magic neutron ~proton! numbers. The new forces describe the experimental systematics similarly to conventional nonlinear s2v relativistic force parameters like NL3.
