Abstract

Cluster radioactivity is an exotic nuclear decay observed in actinides where a light nucleus is emitted while the remaining heavy mass residue is the doubly magic ²⁰⁸Pb or a nucleus in its neighborhood. We have investigated this type of decay in heavier nuclei up to Lv (Z=116) within a microscopic theory. It has been found that the cluster radioactivity known in the light actinides may become the dominant decay channel in some superheavy nuclei. This superasymmetric fission channel is distinct from typical asymmetric fission in actinides. We predict a sharp fission fragment mass distribution with the heavy fragment close to ²⁰⁸Pb.
