在具有随时间变化的衰变率的核half-life测量中环境影响的分析
Analysis of environmental influences in nuclear half-life measurements exhibiting time-dependent decay rates
摘要：
在最近的一系列论文中，已经提出了太阳活动和核衰变速率之间相关性的证据。这包括地球-太阳距离与布鲁克海文国家实验室（BNL）和联邦物理技术研究所（PTB）的数据之间的明显相关性。虽然这些相关性可能是由于衰变核与太阳辐射的某些粒子或场之间的直接相互作用引起的，但它们也可能是由于温度、相对湿度、背景辐射等变化引起的BNL和PTB探测器灵敏度季节性变化引起的“环境”效应。我们对BNL和PTB实验中实际使用的探测器的响应进行了详细的分析，并表明各个探测器对季节性变化的敏感性可能太小而不能产生所观察到的波动。
英文摘要：
In a recent series of papers evidence has been presented for correlations between solar activity and nuclear decay rates. This includes an apparent correlation between Earth-Sun distance and data taken at Brookhaven National Laboratory (BNL), and at the Physikalisch-Technische Bundesanstalt (PTB). Although these correlations could arise from a direct interaction between the decaying nuclei and some particles or fields emanating from the Sun, they could also represent an "environmental" effect arising from a seasonal variation of the sensitivities of the BNL and PTB detectors due to changes in temperature, relative humidity, background radiation, etc. In this paper, we present a detailed analysis of the responses of the detectors actually used in the BNL and PTB experiments, and show that sensitivities to seasonal variations in the respective detectors are likely too small to produce the observed fluctuations.
