The half-life of the extinct radiolanthanide , important for both geochronological and astrophysical applications, was re-determined by a combination of mass spectrometry and -decay counting. Earlier studies provided only limited information on all potential factors that could influence the quantification of the half-life of . Thus, special attention was given here to a complete documentation of all experimental steps to provide information about any possible artifacts in the data analysis. The half-life of was derived to be 92.0 Ma ± 2.6 Ma, with an uncertainty coverage factor of .
对于地质年代学和天体物理学应用都很重要的已灭绝放射性镧系元素 的半衰期，通过质谱法和β衰变计数相结合的方法重新测定。早期研究仅提供了关于所有可能影响 半衰期定量的潜在因素的有限信息。因此，这里特别关注所有实验步骤的完整记录，以提供有关数据分析中任何可能假象的信息。 的半衰期推导为92.0百万年±2.6百万年，不确定度覆盖因子为 。
