Abstract

Calculations of half-lives of superheavy (SH) nuclei show an unexpected result: for some of them cluster radioactivity (CR) dominates over $\ensuremath{\alpha}$ decay. We changed the concept of CR to allow emitted particles with ${Z}_{e}g28$ from parents with $Zg110$ (daughter around ${}^{208}$Pb). We find a trend toward shorter half-lives and larger branching ratios relative to $\ensuremath{\alpha}$ decay for heavier SHs. A table of measured masses along with theoretical tables are used to determine Q values.
