“…For example, very recently, Jin et al have investigated that the enhanced triple-α reaction reduces proton-rich nucleosynthesis in supernovae using SkyNet [43]. The recent experiment on 39 Na has attracted great interests for theorists [32,45]. 39 Na has a magic neutron number of N =28 but has a well prolate deformation and a deformed halo structure [32].…”

“…Semimicroscopic and phenomenological models can be precise for known nuclei but could be less reliable for explorations. As a suitable tool, the density functional theory with high-precision effective interactions are versatile for reasonable descriptions of global finite nuclei and neutron stars, including exotic structures and dynamics of halo nuclei, and nuclear fission [8,[25][26][27][28][29][30][31][32]. Previously the properties of 39 Na and neighboring drip line nuclei have been studied [32].…”

Motivated by the newly observed 39 Na in experiments, systematic calculations of global nuclear binding energies with seven Skyrme forces are performed. We demonstrate the strong correlation between the two-neutron separation energies (S2n) of 39 Na and the total number of bound nuclei of the whole nuclear landscape. Furthermore, with calculated nuclear masses, we perform astrophysical rapid-neutron capture process (r-process) simulations by using nuclear reaction code TALYS and nuclear reaction network code SkyNet. r-process abundances from ejecta of neutron star mergers and core-collapse supernova are compared. Prominent covariance correlations between nuclear landscape boundaries and neutron-rich r-process abundances before the third peak are shown. This study highlights the needs for further experimental studies of drip-line nuclei around 39 Na for better constraints on nuclear landscape boundaries and r-process.

We have employed the relativistic Hartree-Bogoliubov (RHB) model with density-dependent meson-exchange interaction and separable pairing to investigate neutron dripline mechanisms for heavy Mg isotopes. In the present study, 40Mg is predicted to be dripline nuclei. The calculations are carried out by taking axial deformation into account. An investigation of shape transition is also done for even-even 32-42Mg isotopes. Our prediction for neutron dripline for 40Mg is consistent with some recent studies.
