Abstract

This study focusses on identification and analysis of possible isotopes of the superheavy element Roentgenium (Z = 111) by studying competition between the decay modes of the 259-300Rg isotopes. It is also parameterized an equation for the fusion barrier height and position. After this we have also identified the possible projectile-target combinations to synthesize 268-279Rg by studying compound nucleus formation probability, survival probability, and evaporation residue cross sections. The selected projectile-target combinations to synthesize the superheavy element Z = 111 with the combinations are 58Ni+210Bi, 59,60Co+210Po,35,36Cl+236Pu, 35Cl+239-242Pu, 36Cl+238,242,244Pu. The present work is compared with the experimental values available in literature.
