The exotic decay or cluster radioactivity is the radioactive decay at which the nuclei emitting particle heavier than α-particle. This cold process is intermediate between α- decay and spontaneous fission. Sandulescu et al. [1] was first predicted this phenomenon on the basis of quantum mechanical fragmentation theory (QMFT). Spontaneous decay of nuclei by emission of clusters heavier than α particle is experimentally established. The emitted 14C, 24, 25, 26Ne, 28 30Mg, 32 ,34Si clusters from heavy nuclei were observed and the half- lives measured [2] . The cluster decay half-lives can be determined theoretically by the one dimensional Wentzel-Kramers Brillouin (WKB) approximation [2] in which the nuclear potential has a significant role. There are many models to calculate the nuclear potential such as the double folding model (DFM) [3, 4] and liquid drop model [5]. In addition, the proximity potential model has been used to study the cluster radioactivity [6–8]. The importance of this model is that, it provides information about the radioactivity of different nuclei [9]. The Coulomb and Proximity Potential model (CPPM) [10] have been used to study alpha and cluster radioactivity in various mass regions of the nuclear chart.
