Next-generation ab initio shell model for exotic nuclear structures

A symmetry-adapted open-core shell model with SU(3) the underpinning symmetry is described. The model reduces to the well established Elliott SU(3) model in its 0Latin small letter h with strokeΩ limit and to the no-core shell model (NCSM) successful in describing low-energy dynamics of light nuclei if stripped of its special symmetry considerations. We show that this approach is effective in providing an efficient description of low-lying eigenstates of 12C and 16O. A symmetry-guided framework is suggested based on our recent findings of low-spin and high-deformation dominance in realistic NCSM results. This holds promise to significantly enhance the reach of ab initio shell models toward heavier nuclear systems as well as descriptions of collective and cluster phenomena. © 2010 World Scientific Publishing Company.
