Evaporation residue cross section to synthesize superheavy element Z=119

Abstract

The evaporation-residue cross section σ_EVR of fusion reactions depend on the projectile-target combinations and the incident energy. A detail theoretical study is useful before the synthesis of more isotopes of super heavy nuclei Z=119. We have studied the evaporation-residue cross sections for possible projectile-target combinations to synthesis the superheavy nuclei with Z=119. We have studied the dependence of evaporation residue cross section with that of mass number of the target, product of atomic numbers of projectile and target (Z₁Z₂), fusion barrier height (V_b) and fusion barrier width (R_b).  After the detailed analysis, we have identified the most probable projectile-target combinations. The identified projectile-target combinations to synthesis superheavy nuclei ^295-296119 are ⁴⁵Sc+^250,251Cf. We hope that our predictions guide the future experiments in the synthesis of super heavy nuclei ^295-296119.
