Realistic Gamow shell model for resonance and continuum in atomic nuclei

Abstract

The Gamow shell model can describe resonance and continuum for atomic nuclei. The model is established in the complex-moment (complex-k) plane of the Berggren coordinates in which bound, resonant and continuum states are treated on equal footing self-consistently. In the present work, the realistic nuclear force, CD Bonn, has been used. We have developed the full -box folded-diagram method to derive the realistic effective interaction in the model space which is nondegenerate and contains resonance and continuum channels. The CD-Bonn potential is renormalized using the Vlow-k method. With choosing 16O as the inert core, we have applied the Gamow shell model to oxygen isotopes.
