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 alpha-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.
