Synthesis and study of the decay properties of element 110 isotopes: 273Ds and 275Ds
The 232Th( 48 Ca, 5n) 275Ds and 238U( 40Ar, 5n) 273Ds reactions were studied at DGFRS-2 gas-filled separator of the SHE Factory at FLNR JINR. New 275Ds isotope with a half-life of 0.43+0.29-0.12 ms and 11.20±0.02 MeV energy of α-particles was synthesized for the first time in the reaction of 48Ca with the actinide element nuclei and identified by measuring correlated α-decays leading to known nuclei.
