Production of superheavy nuclei in the 48Ca, 50Ti, 51V and 54Cr induced reactions withthe Skyrme energy-density functional

摘要: Within the framework of the dinuclear system model, the synthesis of superheavy nuclei in the48Ca, 50Ti, 51V and 54Cr induced reactions have been systematically investigated. The nucleusnucleus potential and potential energy surface is calculated by the well-known Skyrme energydensity functional theory with the parameters of SKM, SKM*, Ska, Z and SLy4, respectively,which correspond to the different nuclear equation of state. The available experimental data fromDubna, GSI, RIKEN and Berkeley are nicely reproduced. It is found that the incompressibilitymodulus influences the fusion-evaporation residue excitation functions and production cross sectionsof superheavy nuclei. The 48Ca induced reactions, i.e., 48Ca+248Cm have the larger cross sectionsfor synthesizing livermorium in comparison with the systems of 50Ti+244Pu and 54Cr+238U. Theproduction cross sections of new elements with Z=119 and 120 in the reactions of 51V+248Cm
