Cluster Radioactivity in Super Heavy Nuclei

TL;DR

This paper investigates cluster radioactivity in super heavy nuclei up to Z=116 using a microscopic theory, revealing that super asymmetric fission with $^{208}$Pb as a fragment may be a dominant decay mode.

Contribution

It introduces a microscopic theoretical approach to study cluster radioactivity in super heavy nuclei, highlighting the potential dominance of super asymmetric fission channels.

Findings

Super asymmetric fission with $^{208}$Pb as a fragment may dominate decay in some super heavy nuclei.

Cluster radioactivity is closely related to super asymmetric fission.

The study extends understanding of decay modes in nuclei up to Z=116.

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 $^{208}$Pb 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 super asymmetric fission with $^{208}$Pb as heavy fragment may be dominant decay channel in some super heavy nuclei. This reaction is closely related with cluster radioactivity.
