摘要

Experiments on the synthesis of isotopes of element 114 in the 242Pu + 48Ca reaction were carried out at a new gas-filled separator DGFRS-2 online to the DC-280 cyclotron of the Superheavy Element Factory at FLNR JINR. The decay properties of 286Fl and 287Fl, as well as their α-decay products, were refined. The possibility of the existence of isomeric states in successive α-decays of 287Fl is discussed. The maximum cross section of \(10.4_{{ - 2.1}}^{{ + 3.5}}\) pb was measured for the 242Pu(48Ca, 3n)287Fl reaction.
