Anomalous oscillations in beta-decay have been noticed in data sets across the world, from many different investigators, and in the widest array of instrument types. Scientific literature contains many references to the phenomena which often includes annual periodicities with phase relationship to the earth’s annual orbit about the sun as well as solar-mechanical periodicities which relate to the internal motions of the sun. Over time two camps have appeared in the literature - those who hold that the signals are due to environmental effects or instrument errors, and those who propose new physics based on solar neutrino flux.

Here, with a combination of literature review, published experiments, previously unpublished laboratory experiment, and computational machine learning prediction, we advance toward answering the question of which of these two competing hypotheses are correct and propose a design for the next generation of experimental apparatus.
