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

Investigation the isotopic dependence of actinide targets is im portant for selecting optimal reaction systems. Based on the dinuclear system model, the impact of the target isotope is investigated for the reactions 48Ca+239,240,242,244Pu.

The reaction systems with the 242−248Cm tar gets and the 45Sc, 50Ti, 51V, 54Cr, 55Mn projectiles are investigated for the synthesis of new isotopes 284−290Ts, 289−293,295Og, 290−296119, 293−299120, 294−300121. The isotopic dependence of the Cm targets revealed an ascending trend of the maximal ER cross section coupled with an odd-even effect as the neutron number of the target increased, and the 247Cm target emerged as promising for future experiments.
