Abstract

The half-life of41Ca has been redetermined to be (1.01 ±0.10)×105 yr from the specific activity of a sample of enriched calcium material and its41Ca concentration. The activity was measured with a Si(Li) detector via the 3.3-keV X rays emitted in the electron capture decay of41Ca to41K. The41Ca concentration was measured by mass spectrometry. Since our result agrees well with the two most recent half-life measurements of Mabuchi et al. (1974), (1.13±0.12)×105 yr, and Klein et al. (1990), (1.03±0.07)×105 yr, we recommend the weighted mean of these three measurements, t1/2=(1.04±0.05)×105 yr, as the most accurate value of the half-life of41Ca.
