寻找太阳耀斑与放射性核衰变率之间的相关性

Search for correlations between solar flares and decay rate of radioactive nuclei

E. Bellotti, C. Broggini, G. Di Carlo, M. Laubenstein, R. Menegazzo

摘要:

用NaI和Ge探测器测量了~(40)K、~(137)Cs和~(137)natTh三种不同放射源的衰变率。对数据进行了分析,以寻找与2011年和2012年两次最强的太阳耀斑相一致的可能变化。未观察到与标准预期的显著偏离,灵敏度为10-4。因此,我们找不到任何像Jenkins和Fischbach最近报道的那样的效应:在2006年12月的太阳耀斑期间,54 Mn的衰变率降低了每百万分之几。

英文摘要:

The deacay rate of three different radioactive sources 40K, 137Cs and natTh has been measured with NaI and Ge detectors. Data have been analyzed to search for possible variations in coincidence with the two strongest solar flares of the years 2011 and 2012. No significant deviations from standard expectation have been observed, with a few 10-4 sensitivity. As a consequence, we could not find any effect like that recently reported by Jenkins and Fischbach: a few per mil decrease in the decay rate of 54Mn during solar flares in December 2006.
