Experiments on the Synthesis of Superheavy Elements with 48CA Beams at the Separator Vassilissa

The study of the decay properties and formation cross sections of the isotopes of elements 110, 112 and 114 were performed at the FLNR JINR with the use of the high intensity ⁴⁸Ca beams and an electrostatic separator VASSILISSA. ²³²Th, ²³⁸U and ²⁴²Pu targets were used in the experiments. At the beam energies corresponding to the calculated cross section maxima of the 3n evaporation channels the isotopes ²⁷⁷110, ²⁸³112 and ²⁸⁷114 were produced and identified. The cross section limits were obtained at excitation energies of the compound nucleus corresponding to the maxima of the 4n evaporation channels for the reactions with ²³²Th and ²³⁸U targets.
