Investigation of the isotopic dependence in the synthesis of superheavy nuclei with Plutonium and Curium targets

Using the dinuclear system model, this study examined the reaction systems employing ²⁴²Cm to ²⁴⁸Cm targets with ⁴⁵Sc, ⁵⁰Ti, ⁵¹V, ⁵⁴Cr, and ⁵⁵Mn projectiles, providing possible reaction systems toward elements 119–121. The predicted maximum evaporation-residue cross sections generally increase as the curium target becomes more neutron rich, while also showing a clear odd-even staggering pattern. By separating the capture, fusion, and survival stages, the study shows that the isotope dependence arises mainly from the survival process. ²⁴⁷Cm consequently emerges as a promising candidate target for future experiments.
