摘要：

Calculations of half-lives of superheavy nuclei (SH) show art unexpected result: For come of them heavy particle radioactivity (HPR) dominates over alpha decay (branching ratios larger than 1). The new mass table AME11 and the theoretical KTUY05 and FRDM95 masses are used to determine (Q-values. For Z = 124 we found isotopes with half-lives in the range of us to ps.
