Abstract

Experiments using a Ca48 beam on U238 and Pu242 targets to produce superheavy nuclei were performed at the gas-filled separator DGFRS-2 online to the new cyclotron DC280 at the SHE Factory at JINR. The decay properties of Fl286 and Fl287, as well as their α-decay products, were refined after the detection of 25 and 69 new decay chains, respectively. In addition, 16 decay chains of Cn283 were observed in the U238+Ca48 reaction. The possibility of existing of isomeric states in the Fl287 consecutive α decays is discussed. A new α line with an energy of 100-200 keV lower than the main one at 10.19 MeV was observed for the first time for even-even Fl286 decay. A maximum cross section of 10.4-2.1+3.5pb was measured for the Pu242(Ca48,3n) Fl287 reaction.
