Precise and direct determination of the half-life of 41Ca

Jorg, Gerhard; Amelin, Yuri; Kossert, Karsten; Gostomski, Christoph Lierse v


Calcium-41 plays an important role in the long-term evaluation of the safety of final repositories for nuclear waste and is used to study the fine-scale chronology of the formation of the Solar System. Both applications are hindered by insufficient precision and poor consistency of previous determinations of the half-life. This work reports a half-life for41Ca of (9.94±0.15)×104years, which was determined with a combination of methods, chosen to provide the best possible precision. The activity...[Show more]
