1991An10 (also 1991An13, 1994Ye08): 224U produced and identified in 208Pb(20Ne,4n) reaction at E=100-125 MeV, in-flight kinematic separation, and genetic relationships. Measured Eα, T1/2. In 1994Ye08, 197Au+27Al reaction was used to produce 224U.
1992To02: 224U produced in 209Bi(19F,4n) at E=102-115 MeV, velocity filter; measured Eα, T1/2
