摘要
The 232Th(48Ca, 5n)275Ds and 238U(40Ar, 5n)273Ds 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 275Ds with a half-life of 0.43+0.29 -0.12 ms and alpha-particle energy of 11.20 +/- 0.02 MeV was synthesized in the 48Ca-induced reaction with the actinide nucleus and identified by measuring correlated alpha decays ending in known nuclei. The decay properties of nuclei originating from 273Ds and 275Ds are compared with theoretical calculations and decay schemes are proposed. The cross sections of the 232Th(48Ca, 5n)275Ds reaction of 0.11+0.46 -0.09 and 0.34+0.59 -0.16 pb were measured at excitation energies of the 280Ds compound nucleus E & lowast; = 51 and 56 MeV, respectively. The cross section of the 5n-evaporation channel of the 238U + 40Ar reaction at E & lowast; = 49 MeV of 0.18+0.44 -0.12 pb turned out to be comparable to that for 275Ds at close excitation energy.
