摘要：
Calculations of half-lives of superheavy (SH) nuclei show an unexpected result: for some of them cluster radioactivity (CR) dominates over a decay. We changed the concept of CR to allow emitted particles with Z(e) > 28 from parents with Z > 110 (daughter around Pb-208). We find a trend toward shorter half-lives and larger branching ratios relative to alpha decay for heavier SHs. A table of measured masses along with theoretical tables are used to determine Q values.
