Systematic investigation of the formation of superheavy nuclei in the reactions of 48Ca, 50Ti, 51V, and 54Cr on actinide nuclei

Original data on the formation of superheavy nuclei in the 48Ca, 50Ti, 51V and 54Cr induced fusion reactions on actinide nuclei 232Th, 231Pa, 238U, 237Np, 242,244Pu, 243Am, 245,248Cm, 249Bk, 249Cf 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.
