Abstract:
We tabulate the atomic mass excesses and nuclear ground-state
deformations of 8979 nuclei ranging from 16O to A=339. The
calculations are based on the finite-range droplet macroscopic model
and the folded-Yukawa single-particle microscopic model. Relative to
our 1981 mass table the current results are obtained with an improved
macroscopic model, an improved pairing model with a new form for the
effective-interaction pairing gap, and minimization of the ground-state
energy with respect to additional shape degrees of freedom. The values
of only nine constants are determined directly from a least-squares
adjustment to the ground-state masses of 1654 nuclei ranging from
16O to 263106 and to 28 fission-barrier heights. The error of
the mass model is 0.669 MeV for the entire region of nuclei
considered, but is only 0.448 MeV for the region N > 64.
