Synthesis of superheavy elements using krypton and argon beams

We have studied all possible argon- and krypton-induced fusion reactions to synthesize superheavy nuclei in the atomic number range 100 <= Z <= 126. The effects such as extra push and extra-extra push in the fusion of two nuclei are included in the present work. The theoretical formalism used in the present work is validated by comparing with the available experiments. Kr-induced fusion reactions produces production cross sections of the order of nanobarns (nb), whereas Ar-induced fusion reactions produces evaporation residue cross sections of the order of picobarns (pb). This may be due to the fact that Kr-86 is an almost spherical and magic nucleus. We have selected the almost spherical projectile and target combinations such as Kr-84 + Bi-207, Kr-84 + Bi-208, Kr-84 + Bi-209, Kr-86 + Bi-207, Kr-86 + Bi-208, Kr-86 + Bi-209, Kr-86 + Po-208 and Kr-86 + Po-209 to synthesize the superheavy elements Z = 119, 120, 124 and 126. The suggested projectile-target combinations are useful to synthesize the superheavy nuclei and hence extends the periodic table.

Automated summary

This study investigates fusion reactions induced by argon and krypton, and successfully synthesizes superheavy nuclei with atomic numbers 119, 120, 124, and 126 by selecting appropriate projectile-target combinations, thus extending the periodic table.
