New isotope Ds 276 and its decay products Hs 272 and Sg 268 from the Th 232 + Ca 48 reaction
Original language description
The Th232+Ca48 reaction has been studied at the gas-filled separator DGFRS-2 online to the cyclotron DC280 at the SHE Factory at JINR. Three new nuclides were synthesized for the first time: a spontaneously fissioning (SF) Sg268 with the half-life TSF=13+17-4 s; an α decaying Hs272 with Tα=0.16+0.19-0.06 s and Eα=9.63±0.02MeV; and Ds276 with T1/2=0.15+0.10-0.04 ms, Eα=10.75±0.03MeV, and an SF branch of 57%. The decay properties of these nuclei are in agreement with the systematics of experimental partial half-lives and α-decay energies of heavy known nuclei, as well as spontaneous-fission half-lives. The cross sections of the 4n-evaporation channel of 0.07+0.17-0.06 pb, 0.7+1.1-0.5 pb, and 0.11+0.46-0.09 pb were measured at 231, 238, and 251 MeV, respectively.
