Abstract

We study neutron- and proton-rich nuclei with an extended cluster-orbital shell model (COSM) approach, which we call Neo-COSM. The binding energies and r.m.s. radii of oxygen isotopes are reproduced. For N = 8 isotones, the tendency of the abrupt increase of the r.m.s. radii is qualitatively improved.
