Abstract
We tabulate the atomic mass excesses and nuclear ground-state deformat ions of 8979 nuclei ranging from O-16 to A = 339. The calculations are based on the finite-range droplet macroscopic model and the folded-Yu kawa single-particle microscopic model. Relative to our 1981 mass tabl e the current results are obtained with an improved macroscopic model, an improved pairing model with a new form for the effective-interacti on pairing gap, and minimization of the ground-state energy with respe ct to additional shape degrees of freedom. The values of only nine con stants are determined directly from a least-squares adjustment to the ground-state masses of 1654 nuclei ranging from O-16 to (263)106 and t o 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 greater than or equal to 65. (C) 1995 Academic Press, In c.
