The convergence of the effective field theory (EFT) approach of Furnstahl, Serot and Tang to the nuclear many-body problem is studied by applying it to selected doubly-magic nuclei far from stability. An independently developed code, which can incorporate various levels of approximation of the chiral effective lagrangi an, is used to solve the self-consistent relativistic Hartree equations. Results are obtained for ground-state properties such as binding energies, single-parti cle level structure, and densities of the selected spherical, doubly-magic nucle i 132-Sn, 100-Sn and 48-Ni, 78-Ni. Calculated spectra of neigh boring nuclei differing by one particle or one hole show agreement with the most recent experimental data. Predictions for nucleon densities are presented.
