Abstract
- A device with the parent $^{229}$Th source was constructed to search for variations of the daughter $^{213}$Po half-life ($T_{1/2} = 4.2$ $\mu$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 $T_{1/2} = 3.705 \pm 0.001$ $\mu$s. The obtained half-life is in good agreement with some of the literature values obtained with great accuracy.<br />Comment: 6 pages, 9 figures; to be published in PEPAN
