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 and α-decay half-life are predicted for the heaviest β-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 the r-process is discussed. © 1980 Springer-Verlag.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
