摘要：

In the heavy-ion complete fusion reaction Pb-208+Ne-20 the new isotopes 223,224U were produced. These nuclei were identified after in-flight separation with the kinematic separator VASSILISSA, followed by their implantation into a passivated ion implanted silicon detector and the observation of the genetic relationships of subsequent alpha-decays. U223 was found to decay with E-alpha = (8780+/-40) keV and T 1/2 = 18(-5)+10 us. For U224 the alpha-line at E-alpha = (8470 +/- 15) KeV and T 1/2 = 0.7(-0.2)+0.5 ms was observed.
