摘要：

构建具有母体$^{229}$ Th源的装置以搜索子体$^{213}$ Po半衰期（$T_{1/2} = 4.2$ $μ$ s）的变化。在对622天间隔（从2015年7月到2017年3月）的数据系列进行处理时，发现了具有振幅$A_{So}=(5.3 \pm 1.1) \times 10^{-4}$的太阳日变化，具有振幅$A_L = (4.8 \pm 2.1) \times 10^{-4}$的月球日变化和具有振幅$A_S = (4.2 \pm 1.7) \times 10^{-4}$的恒星日变化。发现$^{213}$ Po半衰期平均值为$T_{1/2} = 3.705 \pm 0.001$ $μ$ s。所获得的半衰期是在很好的协议与一些文献值获得了很大的准确度。

英文摘要：

A device with the parent $^{229}$Th source was constructed to search for variations of the daughter $^{213}$Po half-life ($T_{1/2} = 4.2$ $μ$s). A solar-daily variation with amplitude $A_{So}=(5.3 \pm 1.1) \times 10^{-4}$, a lunar-daily variation with amplitude $A_L = (4.8 \pm 2.1) \times 10^{-4}$, and a sidereal-daily variation with amplitude $A_S = (4.2 \pm 1.7) \times 10^{-4}$ were found upon proceeding the data series over a 622-day interval (from July 2015 to March 2017). The $^{213}$Po half-life mean value is found to be $T_{1/2} = 3.705 \pm 0.001$ $μ$s. The obtained half-life is in good agreement with some of the literature values obtained with great accuracy.
