    Abstract

    The synthesis of superheavy elements strongly relies on the competition of the quasifission and fusion fission dynamics in the fusion-evaporation reactions. The systematics on the formation of superheavy nuclei in the Ca48, Ti50, V51, and Cr54 induced fusion reactions on actinide nuclei Th232, Pa231, U238, Np237, Pu242,244, Am243, Cm245,248, Bk249, Cf249 has been thoroughly investigated with the dinuclear system model by including the cluster transfer and coupling to the dynamical evolution of the quadrupole deformation parameters. The uncertainties of the fusion-evaporation excitation functions with the mass models of FRDM2012, KTUY05, LDM1966, SkyHFB, WS4 are investigated and compared with the available experimental data from Dubna, GSI, Berkeley, and RIKEN, respectively. The production cross sections, optimal evaporation channels, and beam energies in the synthesis of superheavy elements Z = 119 and 120 were predicted and compared for the different mass models in the reactions of Ti50+Bk249, V51+Cm248, Cr54+Am243, Ti50+Cf249, V51+Bk249, Cr54+Cm248, respectively.
