Cluster radioactivity in 294,296Og

Abstract

Cluster radioactivity is one of the exotic phenomena which offers an alternate emission in heavy and superheavy nuclei in addition to the α-decay and spontaneous fission. In the present work, we predict half-lives of cluster decay in superheavy nuclei 294,296 Og by picking up the emission of all possible even-even isotopes from He to Mo (Z=2-42). These half-lives are compared with the half-lives of α-decay, and accordingly the possibility of most probable cluster emission is ascertained. For these decay processes, the disintegration energies (Q-values) are taken from WS4 mass model. To estimate cluster emission half-lives, we use few widely known empirical formulas i.e. Horoi [

Decay properties of undetected superheavy nuclei with Z > 110

“…In superheavy nuclei, the probability of heavy clusters viz. Se, Br, Kr, Rb, Sr, Y, Zr, Nb, Mo etc is already speculated in several [66][67][68][69][70][71][72][73]. To invoke the competition of various decay modes, we have comprehensively investigated cluster decay half-lives by using universal decay law (UDL) [74] for all the possible isotopes between 111 Z 118 and 161 N 192.…”
