Abstract

PROBLEM- The orthodox expectation is for decay rates to be strictly constant for all types of decay (β+, β-, EC, α). However empirical results show strong evidence for nuclides having variable decay rates, typically evident as periodicity. The volume of data available suggests this is a real phenomenon, not merely a spurious outcome of measurement errors. However the problem is complex because the data are conflicted for different decays. Consequently it is a significant challenge to explain how the variability might arise, what factors could be involved, and how the underlying mechanisms of causality might operate. PURPOSE- This paper develops a theoretical explanation of the variability of nuclide decay rates. APPROACH- The non-local hidden-variable solution provided by the Cordus theory was used, specifically its mechanics for neutrino-species interactions with nucleons. FINDINGS- It is predicted that the β-, β+ and electron capture processes are induced by pre-supply of neutrino-species, and that the effects are asymmetrical for those species. Also predicted is that different input energies are required, i.e. that a threshold effect exists. Four simple non-contentious lemmas are proposed with which it is straightforward to explain why β- and EC would be enhanced and correlate to solar neutrino flux (proximity & activity), and α emission unaffected. It is shown that the concept of a neutrino-species asymmetry makes sense of the broad patterns evident in the empirical data. IMPLICATIONS- The results support the variability of decay rates, on theoretical grounds. The type of decay (β+, β-, EC, α) is found to be a key variable in this theory, as is the type of neutrino species and its energy. ORIGINALITY- The novel contribution is the provision of a theoretical explanation for why decay rates would be variable. A detailed mechanism is presented for neutrino-species induced decay. Also novel is the prediction that the interaction is asymmetrical, and that the energy requirements are different for the various types of decay.

Summary

Introduction

The orthodox expectation is for decay rates to be strictly constant for all types of decay (β+, β-, EC, α). One reason for this position is that there is neither necessity nor no obvious mechanism within the standard model to support variability. Empirical results show strong evidence for variable decay rates. This is evident in the wide variety of results obtained when measuring the decay of the single free neutron (β-) in different experiments (Griffin, 1964) (Wietfeldt & Greene, 2011). The nuclides show variability in decay rates, and this sometimes shows periodicity. The effect is not required or predicted by quantum or any other theory, but neither can those theories prove that decay rates must be fixed
