Gamow Shell Model description of Li isotopes and their mirror partners

Understand

Background: Weakly bound and unbound nuclei close to particle drip lines are laboratories of new nuclear structure physics at the extremes of neutron/proton excess.

• The comprehensive description of these systems requires an open quantum system framework that is capable of treating resonant and nonresonant many-body states on equal footing.
• Purpose: In this work, we construct the minimal complex-energy configuration interaction approach to describe binding energies and spectra of selected 5 $\leq$ A $\leq$ 11 nuclei.
• Method: We employ the complex-energy Gamow shell model (GSM) assuming a rigid $^4$He core.
