Several experiments studying the fission characteristics of various superheavy compound nuclei such as 122* were performed between 2000 and 2004 at the Flerov Laboratory of Nuclear Reactions. Two nuclear reactions were used, namely Cm + Fe and Pu + Ni. The results reveal how superheavy nuclei fission predominantly by expelling closed shell nuclei such as Sn (Z = 50, N = 82). It was also found that the yield for the fusion-fission pathway was similar between Ca and Fe projectiles, suggesting a possible future use of Fe projectiles in superheavy element formation.
