Correlations between nuclear landscape boundaries and neutron-rich r-process abundances

Abstract
Motivated by the newly observed 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 () of 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 (-process) simulations by using nuclear reaction code TALYS and nuclear reaction network code SkyNet. -process abundances from ejecta of neutron star mergers and core-collapse supernova are compared. Prominent covariance correlations between nuclear landscape boundaries and neutron-rich -process abundances before the third peak are shown. This study highlights the needs for further experimental studies of drip-line nuclei around Na for better constraints on nuclear landscape boundaries and -process.
