- 10:15Conclusion
Wir präsentieren ein Protokoll zur Erzeugung eines isotopisch gereinigten Niedrigenergie-229-Ionen-Strahls aus einer 233U-Quelle. Dieser Ionenstrahl dient zur direkten Detektion des 229mTh Bodenzustandszerfalls über den internen Umwandlungszerfallskanal. Wir messen auch die interne Umwandlungslebensdauer von 229mTh.
