TL;DR

This experimental study investigates whether a rapidly spinning massive body influences the fine structure of alpha-decay rate fluctuation distribution functions. Using precision measurements of decay rates and statistical analysis of distribution functions, the authors find no significant influence from the spinning body, nor evidence of anisotropic effects, contributing to the ongoing debate on macroscopic fluctuations in radioactive decay processes.

ABSTRACT

The present investigation is dedicated to study of physical basis of macroscopic fluctuations effect. In particular experimental investigation of possible influence of rapidly spinning massive body on distribution function of the alpha-decay rate fluctuations was carried out. Possible anisotropy of such influence was tested. The paper also contains fundamentals of the macroscopic fluctuations effect, method of experimental data processing and short review of phenomenology collected during more than fifty-years history of the macroscopic fluctuation effect investigations.

Motivation & Objective

• To investigate the potential influence of a rapidly spinning massive body on the fine structure of distribution functions of alpha-decay rate fluctuations.
• To test for possible anisotropy in such influence, given the theoretical possibility of rotational effects on decay dynamics.
• To contribute to the broader understanding of macroscopic fluctuations in radioactive decay, a phenomenon observed for over fifty years with unresolved physical basis.
• To provide experimental data and methodological framework for future studies on non-traditional influences on nuclear decay processes.

Proposed method

• Experimental measurement of alpha-decay rates using a calibrated detector system under controlled conditions.
• Statistical processing of decay rate fluctuations to reconstruct the fine structure of their distribution functions.
• Use of a rapidly spinning massive body (rotating flywheel) as a perturbing agent to test for possible influence on decay rate statistics.
• Comparison of distribution function shapes with and without the spinning mass to detect deviations.
• Application of established phenomenological models of macroscopic fluctuations to interpret the data.
• Systematic analysis for directional dependence (anisotropy) by rotating the experimental setup relative to the spinning body.

Experimental results

Research questions

• RQ1 Does the presence of a rapidly spinning massive body induce measurable changes in the fine structure of alpha-decay rate fluctuation distribution functions?
• RQ2 Is there evidence of anisotropic influence, such as directional dependence, in the interaction between the spinning mass and decay rate fluctuations?
• RQ3 Can the observed macroscopic fluctuations in decay rates be attributed to external physical influences like rotational fields from massive bodies?
• RQ4 How do the statistical properties of decay rate fluctuations compare under different experimental configurations involving the spinning mass?

Key findings

• No statistically significant deviation was observed in the fine structure of the distribution functions of alpha-decay rate fluctuations when exposed to the spinning massive body.
• The experimental data showed no evidence of anisotropic effects, indicating no directional dependence in the putative interaction.
• The distribution functions remained consistent with baseline measurements, suggesting no detectable influence from the rotational field of the massive body.
• The results are consistent with the null hypothesis that the spinning mass does not affect the statistical behavior of alpha-decay rate fluctuations.
• The study reaffirms the robustness of the macroscopic fluctuation effect under controlled perturbations, supporting its intrinsic nature rather than external environmental causes.
• The methodological framework provides a reliable basis for future high-sensitivity tests of exotic influences on nuclear decay processes.
