On external influences on the radioactive decay rate fluctuations

Published Nov 22, 2020• 1 citation

Abstract

The evolution of views on the possibility of external influence on the process of radioactive decay is briefly presented. Such an effect can lead to the appearance of periods in the time series of the radioactive decay rate fluctuations, which have been the subject of intensive study in the last decade. Two mechanisms for identifying periods are considered: the study of deviations from the theoretical curve of the radioactive decay law and the study of the properties of fluctuations. It is shown that the latter method leads to a universal spectrum of periods observed not only in the time series of the radioactive decay rate fluctuations, but also in the time series of fluctuations of processes of various nature. The main object of our study are periods in the radioactive decay rate fluctuations. The presence of such periods suggests the possibility of external influence on the process of radioactive decay. Therefore, we briefly consider the evolution of views on the possibility of such an effect. To do this, we distinguish several stages. The division into stages is only partially historical, but, mainly, each stage characterizes a certain ideas that is implemented in it.

A Hypothesis on State-Dependent Nuclear Decay Rates and Emergent Randomness

Moritz Kopp

This project presents a conceptual and mathematical hypothesis concerning the apparent randomness of radioactive decay. While current nuclear physics models describe decay as a fundamentally stochastic and random process with a constant decay rate, this work explores the possibility that the randomness may come from rapidly fluctuating internal nuclear states that are not directly obsercable by measurement. The central idea is that the effective decay constant measured experimentally represents a time-averaged quantity over a distribution of internal configurations, associated with slightly different decay probabilities. In this framework, radioactive decay remains statistically exponential at observable timescales, while allowing for hidden internal dynamics consistent with established quantum mechanical principles. My work does not claim experimental verification. Instead, it aims to outline a phenomenological structure compatible with known decay laws and to identify conditions under which small, systematic deviations might arise under perturbations.

[Discrete macroscopic fluctuations in processes of various nature].

S E Shnol', Udal'tsova Nv, Bodrova Nb +1 more

The data of 30-year investigations of macroscopic fluctuations are generalized in this review. The results of measuring processes of different nature (from biochemical reactions to radioactive decay) fluctuate. They are presented by certain discrete values. The discreteness of corresponding spectra of states can be probably explained by both pure mathematical causes and cosmophysical factors. The fluctuation amplitude and the shape of the spectrum of the states of objects with different nature depend on the universal external cosmophysical factors. General problems arising in connection with the analysis of the "scatter in the results" and "nonreproducibility of measurements" are discussed.

[Probability of disturbance of Poisson statistics in radioactive decay type processes].

A A Kirillov, K I Zenchenko

The phenomenon of regular dynamics of fine structure of sampling distributions in processes of radioactive decay type is discussed. The time dependence of the probability of their similarity indicates that the process measured is nonstationary. The most natural explanation for the disturbance of stationarity is the influence of gauging equipment, which in principle cannot be avoided completely. However, the universality of the effect and the presence of the correlation of the fine structure in independent synchronous processes leads one to suggest the existence of some global source. A mechanism of the generation of fine structure as a result of the influence of nontrivial topology of space on the decay process is proposed.

Observation of the Influence of an Electromagnetic Field on a Radioactive Decay Rate

V. A. Yatsyshyn, A. D. Skorbun

The influence of the electromagnetic field on the rate of gamma pulses counting from radioactive samples after the action of the driver in the form of pulses of the electromagnetic field was observed. Controlled radionuclide is 137Cs. The sample was a sample of ordinary soil. At a certain time interval, there was an increase in the count rate, and then its decline. The magnitude of changes reached 3%. The observation lasted about one year.

Nuclear Decay Oscillations and Nonlinear Quantum Dynamics

Sergey Nikolaevich Mayburov

Abstract Several experimental groups reported the evidence of periodic modulations of nuclear decay constants which amplitudes are of the order $${{10}^{{ - 3}}}$$ and periods of one year, 24 h or about one month. We argue that such deviations from radioactive decay law can be described in nonlinear quantum mechanics framework, in which decay process obeys to nonlinear Shrödinger equation with Doebner–Goldin terms. Possible corrections to Hamiltonian of quantum system interaction with gravitation field considered, it’s shown that they correspond to some emergent gravity theories, in particular, bilocal field model. It’s shown that proposed model describes decay parameter variations which agree with experimental results for Po-214 $$\alpha $$ -decay life-time oscillations.

Non-exponential and oscillatory decays in quantum mechanics

Murray Peshkin, Alexander Volya, Vladimir Zelevinsky

The quantum-mechanical theory of the decay of unstable states is revisited. We show that the decay is non-exponential both in the short-time and long-time limits using a more physical definition of the decay rate than the one usually used. We report results of numerical studies based on Winter's model that may elucidate qualitative features of exponential and non-exponential decay more generally. The main exponential stage is related to the formation of a radiating state that maintains the shape of its wave function with exponentially diminishing normalization. We discuss situations where the radioactive decay displays several exponents. The transient stages between different regimes are typically accompanied by interference of various contributions and resulting oscillations in the decay curve. The decay curve can be fully oscillatory in a two-flavor generalization of Winter's model with some values of the parameters. We consider the implications of that result for models of the oscillations reported by GSI.
