alpha-decay properties of the new isotope U-216

The new neutron-deficient isotope U-216 was produced in the complete-fusion reaction W-180(Ar-40,(4)n) U-216. The evaporation residues were separated from the primary beam in flight by the gas-filled recoil separator Spectrometer for Heavy Atoms and Nuclear Structure. The activities have been identified by the alpha-alpha position and time correlation measurements. Two alpha-decaying states with E alpha = 8384(30) keV, T-1/2 = 4.72(-1.57)(+4.72) ms for the ground state and E alpha = 10582(30) keV, T-1/2 = 0.74(-0.29)(+1.34) ms for an isomeric state were identified in U-216.
