Abstract

In this paper we predict atomic masses which are not experimentally accessible by using local mass relations which connect with the proton-neutron interactions with improved accuracy. Based on our predicted masses, we investigate one-proton and one-neutron drip lines for a few regions in the nuclide chart and $α$ -decay half-lives times for some isotopes with proton number $102 ⩽ Z ⩽ 106$ . The impact of our predicted one-neutron separation energies on astrophysical $r$ -process nucleosynthesis is discussed within the framework of a classical $r$ -process model.
