Decay properties of undetected superheavy nuclei with Z>110

Abstract

A comprehensive study of favoured and unfavoured $\alpha$-decay, cluster decay, weak-decay along with spontaneous fission in undetected superheavy nuclei within the range for proton number 111$\le$Z$\le$118 and neutron number 161$\le$N$\le$192 is performed. Half-lives for various mentioned decays are estimated with good accuracy on the basis of NUBASE2020 and are found in excellent match with the known half-lives. $\alpha$-decay mode is found most probable in this wide range and correspondingly potential $\alpha$-decay chains are reckoned. Peculiarly, the chances of cluster emission, as well as weak-decay, are also anticipated in this region of the periodic chart which open new pathways of detection of superheavy nuclei.
