Title: Cluster radioactivity of Og 176 118 294

Abstract

According to theory, cluster radioactivity becomes an important decay mode in superheavy nuclei. We suggest that the strongly asymmetric fission, or cluster emission, is in fact the dominant fission channel for Og 176 118 294 , which is currently the heaviest synthetic isotope known. Our theoretical approach incorporates critical features of fission dynamics, including quantum tunneling and stochastic dynamics up to scission. We show that despite appreciable differences in static fission properties such as fission barriers and spontaneous fission lifetimes, the prediction of cluster radioactivity in Og 176 118 294 is robust with respect to the details of calculations, including the choice of energy density functional, collective inertia, and strength of the dissipation term.
