Extension of effective lagrangian approach to structure of selected nucle i far from stability

Abstract

In a previous paper, the convergence of a new effective field theory and density functional theory (EFT/DFT) approach to the description of the nuclear many-body system was studied. The most sophisticated parameter set (here G1) determined by Furnstahl, Serot and Tang from a fit along the valley of stability was found to provide quantitative predictions for total binding energies and single-particle and single-hole binding energies, spins, and parities for selected doubly-magic nuclei far from stability. Binding energies of all the even Sn isotopes (Z=50) were also well described. Here the calculations are extended to all isotones with magic numbers N=28, 50, 82, 126, and isotopes with Z=28, 50, 82 with similar predictive results.
