Abstract
We present results of the first experiment aimed at the synthesis of Mc isotopes in the reaction performed at the new gas-filled separator DGFRS-2 online to the new cyclotron DC280 at the Super Heavy Element Factory at JINR. Fifty-five new decay chains of and six chains assigned to were detected. The decay of with an energy of 7.6–8.0 MeV, half-life of , and a branch of was registered for the first time, and a new spontaneously fissioning isotope with a half-life of was identified. The cross section for the reaction was measured to be pb, which is the largest value for the known superheavy nuclei at the island of stability.
