    Notes: Abstract The previously developed energy density mass formula is extrapolated to the superheavy region and to the neutron drip line. Fission barriers,α-decay andβ-decay energies of isotones withN=184 are computed and half-lives are estimated by using simple corrections to the half-lives obtained by Fiset and Nix. According to the assumption made to extrapolate the pairing parameters, the most stable nucleus atN=184 is found to be either184X 110 294 with a half-life of 67 years, or184 108 292 with a half-life of 13 years. The position of the neutron drip line for 8≦Z≦44 is also studied and compared to the predictions of other mass formulae. Important differences are found, particularly for the influence of the shell effects in this region.

    Shell structure and stability of nuclei with 270〈A〈500 and the possible existence of primordial superheavy nuclei (1980)
    Springer

    Notes: Abstract The self-consistent energy density method is applied to the study of the properties of superheavy nuclei with 270〈A〈500. The shell structure,α-decay energy andα-decay half-life are predicted for the heaviestβ-stable isotope of each even element. The characteristics of nuclear densities and single-particle potentials in the superheavy region are also examined, with a particular attention on the surface diffuseness. After an approximate calculation of their fission barrier heights, only a few heavy isotopes of elements 106 and 108 are predicted to have a small chance to be found in nature. Their possible formation by ther-process is discussed.
