A. %D 2017 %T Spectral Content in 3H and 14C Decays: A Review of Five Experiments %K %X We conduct a generalized spectral analysis of previously published data to re-examine new reports of annual and monthly periodicities in the decay of 3 H and 14 C.  We find no common spectral content in two pairs of simultaneously measured 3 H and 14 C samples, suggesting fluctuations over the nearly nine year experiment are systematic effects rather than evidence of solar influence on decay rates.  Direct comparisons to three other 3 H experiments with anomalous results also suggest the presence of systematic effects rather than the appearance of new physics. %U https://esmed.org/MRA/qpr/article/view/1258 %J Quarterly Physics Review %0 Journal Article %V 3 %N 2 %@ 2572-701X %8 2017-07-01
