Synthesis and decay properties of isotopes of element 110: Ds 273 and Ds 275

Popis výsledku v původním jazyce

The Th232(Ca48,5n)Ds275 and U238(Ar40,5n)Ds273 reactions have been studied at the gas-filled separator DGFRS-2 at the Superheavy Element Factory at Flerov Laboratory of Nuclear Reactions, Joint Institute for Nuclear Research. For the first time, a new isotope Ds275 with a half-life of 0.43-0.12+0.29 ms and α-particle energy of 11.20±0.02 MeV was synthesized in the Ca48-induced reaction with the actinide nucleus and identified by measuring correlated α decays ending in known nuclei. The decay properties of nuclei originating from Ds273 and Ds275 are compared with theoretical calculations and decay schemes are proposed. The cross sections of the Th232(Ca48,5n)Ds275 reaction of 0.11-0.09+0.46 and 0.34-0.16+0.59 pb were measured at excitation energies of the Ds280 compound nucleus E∗=51 and 56 MeV, respectively. The cross section of the 5n-evaporation channel of the U238+Ar40 reaction at E∗=49 MeV of 0.18-0.12+0.44 pb turned out to be comparable to that for Ds275 at close excitation energy.
