Spectral Content in 3H and 14C Decays: A Review of Five Experiments

R. H. Lee, E. Fischbach, J. T. Gruenwald, D. Javorsek II, P. A. Sturrock


We conduct a generalized spectral analysis of previously published data to re-examine new reports of annual and monthly periodicities in the decay of 3H and 14C.  We find no common spectral content in two pairs of simultaneously measured 3H and 14C 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 3H experiments with anomalous results also suggest the presence of systematic effects rather than the appearance of new physics.
