Theoretical estimates of spontaneous-fission half-lives for superheavy elements based on the modified-oscillator model
The stability problem for the superheavy elements has been reconsidered based on the use of the shape-dependent droplet model and the modified-oscillator potential. The effect of axial asymmetry on the barrier heights is included. A semi-empirical inertial-mass function is employed. Alternatively the inertial- mass parameters are calculated microscopically. The spontaneous-fission half- lives are calculated with these inertias. Both of the latter were renormalized to give optimal agreement with experimental half-lives in the actinide region. The resulting spontaneous-fission half-lives in the SHE region are somewhat shorter than those of most previous estimates, predicting, for example, around 10$sup 5$ years as the total half-life for the most stable nucleus $sup 294$110. 8 figures, 1 table.
