Proton-neutron coupling in the Gamow shell model: The lithium chain
Proton-neutron coupling in the Gamow shell model: The lithium chain
The shell model in the complex-$k$ plane (the so-called Gamow shell model) has recently been formulated and applied to the structure of weakly bound, neutron-rich nuclei. The completeness relations of Newton and Berggren, which apply to the neutron case, are strictly valid for finite-range potentials. However, for long-range potentials, such …
