Relativistic Hartree-Bogoliubov description of sizes and shapes of A=20 isobars - art. no. 034305

Ground-state properties of A = 20 nuclei (N-20, O-20, F-20, Ne-20, Na-20, a nd Mg-20) are described in the framework of relativistic Hartree-Bogoliubov theory. The model uses the NL3 effective interaction in the mean-field Lag rangian, and describes pairing correlations by the pairing part of the fini te-range Gogny interaction D1S. Binding energies, quadrupole deformations, nuclear matter radii, and differences in radii of proton and neutron distri butions are compared with recent experimental data.
