Evidence against correlations between nuclear decay rates and Earth–Sun distance

Evidence against correlations between nuclear decay rates and Earth–Sun distance

We have reexamined our previously published data to search for evidence of correlations between the rates for the alpha, beta-minus, beta-plus, and electron capture decays of 22Na, 44Ti, 108Ag m, 121Sn m, 133Ba, and 241Am and the Earth–Sun distance. We find no evidence for such correlations and set...

Zusammenfassung:We have reexamined our previously published data to search for evidence of correlations between the rates for the alpha, beta-minus, beta-plus, and electron capture decays of 22Na, 44Ti, 108Ag m, 121Sn m, 133Ba, and 241Am and the Earth–Sun distance. We find no evidence for such correlations and set limits on the possible amplitudes of such correlations substantially smaller than those observed in previous experiments.
