The new neutron-deficient isotope 216 U was produced in the complete-fusion reaction 180 W( 40 Ar ,4n) 216 U. 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 α-α position and time correlation measurements. Two α-decaying states with E α = 8384(30) keV, T 1/2 = 4.72 +4.72 −1.57 ms for the ground state and E α = 10582(30) keV, T 1/2 = 0.74 +1.34 −0.29 ms for an isomeric state were identified in 216 U.
