We tabulate the ground-state odd-proton and odd-neutron spins and parities, proton and neutron pairing gaps, one- and two-neutron separation energies, quantities related to $\beta$-delayed one- and two-neutron emission probabilities, average energy and average number of emitted neutrons, $\beta$-decay energy release and half-life with respect to Gamow-Teller decay with a phenomenological treatment of first-forbidden decays, one- and two-proton separation energies, and $\alpha$-decay energy release and half-life for 9318 nuclei ranging from 16O to 339136 and extending from the proton drip line to the neutron drip line. This paper is a new and improved version of ATOMIC DATA AND NUCLEAR DATA TABLES [66 131 (1997)]. The starting point of our present work is the new study (FRDM(2012)) of nuclear groundstate masses and deformations based on the finite-range droplet model and folded-Yukawa single-particle potential published in a previous issue of ATOMIC DATA AND NUCLEAR DATA TABLES [109–110, 1 (2016)]. The $\beta$-delayed neutron-emission probabilities and Gamow-Teller $\beta$-decay rates are obtained from a quasi-particle random-phase approximation with single-particle levels and wave functions at the calculated nuclear ground-state shapes as input quantities. A development since 1997 is we now use a Hauser-Feshbach approach to account for (n,$\gamma$) competition and treat first-forbidden decay in a phenomenological approach.
