Evidence of solar influence on the tritium decay rate

The tritium decay rate has been investigated as a function of time. The 27-day and daily variations of counting rate in the high-energy region of the tritium beta spectrum have been obtained. It has been supposed that the 27-day variations could be caused by the interaction of tritium nuclei with low-energy solar neutrinos.

► The 27-day variations seem to be caused by the solar neutrino flux modulation.
