“…Experiments revealed that 31 F is a neutron drip line nucleus [75]. Although our GSM calculations provide a lower energy of 31 F compared to that of 30 F, 31 F is still unbound compared to 29 F. However, our GSM calculations provide good descriptions of ground-state energies for 23−29 F.…”

“…This dramatic change is called an "oxygen anomaly". Moreover, many exotic properties develop at the neutron drip line for fluorine isotopes, such as halos in 29 F [76] and 28 F within the island of inversion around N = 20 [77], and thus fluorine isotopes provide a very interesting ground for theoretical studies.…”

“…One-nucleon densities of the bound 27,29,31 F isotopes calculated with the GSM using the EFT interaction in the valence space as a function of radii r, respectively, depicted by short-dashed, long-dashed, and solid lines. The rms radii of these isotopes are shown in the inset (with permissions from Ref.…”

“…The two-neutron separation energy S 2n of 31 F is about 170 keV [78], which is sufficiently small for sustaining a two-neutron halo. We calculated the one-nucleon densities and neutron rms radii of the neutron-bound 27,29,31 F isotopes using GSM with the EFT interaction (see Figure 7). From our calculations, a halo clearly develops in the asymptotic region of 31 F. Indeed, on the one hand, the one-nucleon density of 31 F slowly decreases on the real axis and is about one to two orders of magnitude larger than those of 27,29 F in the asymptotic region.…”

“…Only few models explicitly include continuum coupling. The main models including both internucleon correlations and continuum coupling in a unified picture are the no-core Gamow shell model (NCGSM) [27][28][29], the no-core shell model with continuum (NCSMC) [30], the complex CC [31,32], the Gamow IMSRG (Gamow-IMSRG) [33], continuum shell model (CSM) [34,35], and the Gamow shell model (GSM) [19,[36][37][38][39], which are extensions of the NCSM, CC, IM-SRG, and SM, respectively. However, due to their huge model space dimensions, the NCGSM and NCSMC can only be used to describe light nuclei [27,28,30].…”

The Gamow shell model (GSM) is a powerful method for the description of the exotic properties of drip line nuclei. Internucleon correlations are included via a configuration interaction framework. Continuum coupling is directly included at basis level by using the Berggren basis, in which, bound, resonance, and continuum single-particle states are treated on an equal footing in the complex momentum plane. Two different types of Gamow shell models have been developed: its first embodiment is that of the GSM defined with phenomenological nuclear interactions, whereas the GSM using realistic nuclear interactions, called the realistic Gamow shell model, was introduced later. The present review focuses on the recent applications of the GSM to drip line nuclei.
