Time-Dependent Nuclear Decay Parameters: New Evidence for New Forces?

RADIOACTIVITY ³H, ¹⁴C, ³²Si, ⁶⁰Co, ¹³⁷Cs(β^-), ²²⁶Ra, ²³⁸Pu(α), ⁵⁴Mn(EC); analyzed available data on possible time-dependence of nuclear decay rates; deduced the possible existence of some new interaction(s) which would be responsible for any observed time variation.

Evidence of correlations between nuclear decay rates and Earth-Sun distance

RADIOACTIVITY ²²⁶Ra(α), ³²Si(β^-), ³⁶Cl(β^-), (EC); analyzed available data for periodic fluctuations in the decay rates at Brookhaven National Laboratory, ³²Si and at the Physikalisch-Technische-Bundesanstalt in Germany, ²²⁶Ra; deduced that the observed fluctuations are strongly correlated in time, not only with each other, but also with the time of year, the possibility that these correlations arise from seasonal influences on the detection system, as well as the suggestion of an annual modulation of the decay rates themselves which vary with Earth-Sun distance.
