摘要：

The alpha-decay and spontaneous fission (SF) half-lives of nuclei around (220)Hs are calculated with formulas derived from the systematics of data and theoretical results. The coefficients of the systematics result from the fit of half-lives in respect with the reaction energies Q(alpha), the height of the SF barrier B-f and the fissionability Z(2) / A. The calculated partial and total half-lives are compared with the data and the results of other approximations. Half-life predictions are made for many unknown nuclei.
