Abstract
The pulsed nuclear reactor was used to measure the effect of neutrinos on the beta-decay of 90Sr/90Y nuclei. This measurement shows that some increase in the decay rate occurs in a few tens of milliseconds after reactor flashes.
Highlights
The state of radioactive nuclei is energetically unstable
If the β-decay of nuclei would be caused only by the solar neutrino flux, we can expect that the rate of β-decay in the terrestrial laboratory must be modulated to a depth of 7% with a period equal to year
The results of measurements show that the flux of reactor neutrinos does have some quite noticeable effect on the phenomenon of beta-decay
Summary
The state of radioactive nuclei is energetically unstable. At decay, they pass from a certain excited state to a state with lower energy. It can be assumed that in order to cause a radioactive decay occurring with the energy releasing, a quasi-elastic collision of neutrino with a nucleus is enough. The time of its life defies calculation According to this model, proton and electron forming the neutron are bound by electromagnetic forces. We can assume that β-decay is a forced phenomenon that occurs under the external influence of the neutrino flux. This assumption can be verified if the correlation between the neutron lifetime or the rate of the nuclei β-decay and the intensity of the neutrino flux incident on them can be studied
