Аннотация
We report the experimental confirmation of the production of element 110. In the bombardment of a 208 Pb target with a 309-MeV 64 Ni beam, we have observed two chains of time-and position-correlated events. Each chain consisted of the implantation of an evaporation residue followed by the emission of particles. We attribute these two chains to the decay of 271 110 produced with a cross section of 8.3 5.3 11 pb.
