Title: Lifetimes of superheavy nuclei around double magic nucleus {sup 270}Hs

The α-decay and spontaneous fission (SF) half-lives of nuclei around 270Hs are calculated with formulas derived from an in-depth analysis of the available experimental data and from theoretical models. The parameters of these formulas result from the fit of half-lives with respect to the reaction energies Q{sub α}, the height of the SF barrier B{sub f} and the fissionability Z{sup 2}/A. The calculated partial and total half-lives are compared with the experimental data and the results of other approximations. Half-life predictions are made for many unknown nuclei.
