Masses and Deformations of Neutron-rich Nuclei

We have calculated the masses, deformations, and other properties of 8979 nuclei ranging from O to 136 and extending from the proton drip line to the neutron drip line on the basis of the 1992 version of the finite-range droplet model. The predicted quantities include the ground-state mass, deformation, microscopic correction, odd-proton and odd-neutron spins and parities, proton and neutron pairing gaps, binding energy, oneand two-neutron separation energies, quantities related to β-delayed oneand two-neutron emission probabilities, β-decay energy release and half-life with respect to Gamow-Teller decay, oneand two-proton separation energies, and α-decay energy release and half-life. For 1654 nuclei heavier than O 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 O 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.
