Abstract

In the heavy-ion complete fusion reaction208Pb+20Ne the new isotopes223,224U 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 α-decays.223U was found to decay withE α=(8780±40) keV and T1/2=18 +10−5 μs. For224U the α-line atE α=(8470±15) keV and T1/2=0.7 +0.5−0.2 ms was observed.
