From Nuclear Astrophysics to Superheavy Elements: Predictions for Nuclei Beyond Our Shores

Summary: | Properties of 8,979 nuclei ranging from oxygen-16 to Z = 136, A = 339 and
extending from the proton drip line to the neutron drip line have been
calculated by use of the 1992 version of the finite-range droplet model. The
calculated quantities include the ground-state mass, deformation, microscopic
correction, odd-proton and odd-neutron spins and parities, proton and neutron
pairing gaps, binding energy, one- and two-neutron separation energies,
quantities related to beta-delayed one- and two-neutron emission probabilities,
beta-decay energy release and half-life with respect to Gamow-Teller decay,
one- and two-proton separation energies, and alpha-decay energy release and
half-life. For 1,654 nuclei heavier than oxygen-16 whose masses were known
experimentally in 1989 and which were included in the adjustment of model
constants, the theoretical error is 0.669 MeV. For 371 additional nuclei
heavier than oxygen-16 whose masses have been measured between 1989 and 1996
and which were not used in the adjustment of the model constants, the
theoretical error is 0.570 MeV. We also discuss the extrapolateability of two
other recent global models of the macroscopic-microscopic type, and conclude
with a brief discussion of the recently discovered rock of metastable
superheavy nuclei near Z = 110, A = 272 that had been correctly predicted by
macroscopic-microscopic models. |
