Abstract

Exotic decay of some heavy nuclei with Z≥100 formed in heavy ion ‘cold fusion’ reaction were studied taking interacting barrier consisting of Coulomb and proximity potential. Calculated half-life time shows that some modes of decay are well within the present upper limit for measurements (T 1/2<1030 s). Cluster formation probabilities are calculated for different clusters within fission model. It is found that transition from cluster mode to fission mode take place at mass of the cluster, A 2=20 in exotic decay which is comparable with the value A 2=16 of Shanmugam et al based on cubic plus Yukawa plus exponential model (CYEM).
