Synthesis of superheavy element Z=121

Superheavy elements (SHEs) up to Z=118 have been prepared in the laboratory till now and endeavour to produce Z=119 and Z=120 is going on. The fusion reactions include the complete fusion followed by fission or evaporation residue as well as quasi-fission processes where there are mass transfers which occur in a short time scale. The relative contributions of these processes are estimated from the different variables such as entrance channel asymmetry, excitation energy, fission and quasi-fission barrier etc. In the present work our aim is to predict the evaporation residue cross section for the synthesis of SHE, Z=121 using the reaction ⁴⁸Ca+²⁵⁸Md→³⁰⁶121, ⁵⁰Ti+²⁵⁴Es→³⁰⁴121, ⁵⁰Ti+²⁵²Es→³⁰²121 and ⁵⁴Cr+²⁴⁹Bk→³⁰³121
