$\rm{^{123}I}$和$\rm{^{99m}Tc}$衰变率测量的广义Lomb-Scargle分析

Generalized Lomb-Scargle analysis of $\rm{^{123}I}$ and $\rm{^{99m}Tc}$ decay rate measurements

Gautham Gururajan, Shantanu Desai

摘要:

我们应用广义Lomb Scargle周期图的$\rm{^{123}I}$和$\rm{^{99m}Tc}$衰变率测量的基础上采取的数据在布朗森卫理公会医院。这项工作的目的是进行一个独立的搜索正弦调制这些放射性核素(以补充在Borrello等人的分析)的频率,其他放射性核素显示周期性。我们在任何频率上都没有发现这种调制的证据,包括年度调制或与太阳旋转相关的频率。我们的分析代码和数据集已公开提供。

英文摘要:

We apply the generalized Lomb-Scargle periodogram to the $\rm{^{123}I}$ and $\rm{^{99m}Tc}$ decay rate measurements based on data taken at the Bronson Methodist Hospital. The aim of this exercise was to carry out an independent search for sinusoidal modulation for these radionuclei (to complement the analysis in Borrello et al) at frequencies for which other radionuclei have shown periodicities. We do not find evidence for such a modulation at any frequencies, including annual modulation or at frequencies associated with solar rotation. Our analysis codes and datasets have been made publicly available.
