Probable cluster decays from ${}^{270-318}$118 superheavy nuclei

Abstract

The cluster decay process in ${}^{270-318}$118 superheavy nuclei has been studied extensively within the Coulomb and proximity potential model (CPPM), thereby investigating the probable cluster decays from the various isotopes of $Z=118$. On comparing the predicted decay half lives with the values evaluated using the Universal formula for cluster decay (UNIV) of Poenaru et al., the Universal Decay Law (UDL) of Qi et al., and the Scaling Law of Horoi et al., it was seen that, our values matches well with these theoretical values. A comparison of the predicted alpha decay half life of the experimentally synthesized superheavy isotope ${}^{294}$118 with its corresponding experimental value shows that, our theoretical value is in good agreement with the experimental value. The plots for $lo{g}_{10}(T_{1/2})$ against the neutron number of the daughter in the corresponding decay reveals the behavior of the cluster half lives with the neutron number of the daughter nuclei and for most of the decays, the half life was found to be the minimum for the decay leading to a daughter with $N=184$. Most of the predicted half lives are well within the present experimental upper limit ($10^{30}$s) and lower limit ($10^{-6}$s) for measurements and hence these predictions may be of great use for further experimental investigation on cluster decay in the superheavy region.
