Study of competing fission and quasifission modes involved in ⁵⁴Cr+²⁴⁸Cm leading to formation of superheavy nucleus ^AZ = ³⁰²120

The understanding of the interplay between fusion-fission (FF) and quasifission (QF) processes among superheavy nuclei (SHN), particularly for proton shell closures (i.e., Z=114, 120), at near barrier energies are presently the most important in searching pathways to synthesize new superheavy elements (SHEs). The unsuccessful efforts to synthesize SHEs Z=120 using ⁵⁸Fe and ⁶⁴Ni beams lead to intense attention towards ^54,52Cr projectiles. A recent report on irradiation of ²⁴⁸Cm with ⁵⁴Cr gives a signature of α-decay chain starting from an isotope of Z=120. However, critical reanalysis of the data confirms that three α-event chain was actually a random sequence of events. Hence the present scenario intrigues for further experimental investigations for the measurements of compound nucleus fusion probability (PCN) at near barrier energies which may play an important role to understand the underlying reaction processes
