NUCLEAR-MASS FORMULA VIA AN APPROXIMATION TO THE HARTREE-FOCK METHOD

We present the first nuclear mass table to be based entirely on microscopic forces. The calculations are performed using the extended Thomas-Fermi plus Strutinsky integral method, a semiclassical approximation to the Hartree-Fock method that includes full Strutinsky shell corrections; BCS pairing corrections are added, The eight active parameters of the underlying Skyrme and delta-function pairing forces are fitted to all the 1492 mass data (1988 compilation) for A greater than or equal to 36; the rms error of this fit is 0.736 MeV. Our tabulation covers the range 36 less than or equal to A less than or equal to 300 and reaches beyond the neutron- and proton-drip lines. In addition to the calculated masses, we show the calculated neutron- and proton-separation energies and beta-decay energies; We also give for each nucleus in the table the model predictions for the deformation parameters and deformation energy at equilibrium (with axial and left-right symmetry assumed) and for the charge radii.
