Abstract

In a number of experiments, when detecting particles emitted in beta decays, periodic oscillations of count rate with an amplitude up to tenths of a percent and short bursts vastly exceeding the usual count rate are found. At the same time, several experiments did not detect any differences from the “normal” course of beta decays greater than 0.01%. The article shows that the inconsistency of the experimental results is due to different measurement technique. The assumption is made of the possible participation in the beta decay processes of cosmic slow neutrinos, which makes it possible to explain in a comprehensive manner not only periodic and sporadic changes in the beta decay rate, but also a number of other incomprehensible phenomena associated with beta radioactivity. On the basis of the experiments carried out, an estimate is made of the flux density of slow cosmic neutrinos.

Strong outbursts of beta particles count rate are detected with the continuous scanning of the celestial sphere by peculiar telescopes in which the beta source is located in the focus of the parabolic mirror

Summary

Introduction

The strictly exponential nature of radioactive nuclides decay rate was considered unquestionable. Let us assume that the anomalies in the beta decay rate are associated with the action of neutrinos or antineutrinos in accordance with nuclear reactions νe + ( A, Z ) → ( A, Z +1) + e−. This occurs against the backdrop of spontaneous decays ( A, Z ) → ( A, Z +1) + e− +ν e or ( A, Z ) → ( A, Z −1) + e+ +νe (2). If the number of induced reactions is much less than the number of spontaneous decays, in order to detect effects associated with the action of neutrinos (antineutrinos), it is necessary to have detectors that can selectively register electrons (positrons) with an energy exceeding Emax. This article will describe some of the results obtained by the author of this article
