Binary and ternary fission analysis of Es nucleus using collective clusterization approach

Sometimes one finds three fragments in the outgoing channel instead of usual binary decay, and such kind of process is termed as ternary fission. Generally, the third fragment of ternary fission decay is lighter in comparison to other two main fission fragments, therefore also known as light particle-accompanied fission. The decay of heavier third fragment is also possible for the case of very heavy and superheavy nuclei. The ternary fission was reported for the first time by Alvarez et al. in 1947 [1]. Until now, many theoretical and experimental studies have been done to analyze the yield of different fragment channels for the particle-accompanied fission of heavy radioactive nuclei. In the present work, the decay of Es is analyzed in view of binary and ternary fission channels. For this nucleus, the possibilities of several third fragments of ternary fission such as H, He and Li are investigated. Apart from this, a relative study of binary fission (decay in two fragments) and ternary fission of Es is carried out in terms of fragmentation structure is within the framework of collective clusterization process. The most probable decay fragments in these two fission decay processes are also identified.
