Experimental investigations of changes in the rate of beta decay of radioactive elements

Changes in the rate of the beta decay of radioactive elements whose periods are about 24 h and 27 d are detected on the basis of long-term investigations performed with the aid of scintillation and germanium-lithium gamma detectors. The use of the scintillation procedure yields results whose level of significance is much higher than 5%, while the procedure based on germanium—lithium detectors gives a more than 1% deviation from the average value of fluxes of gamma rays accompanying, for example, 60Co beta decay. With allowance for the rotation of the laboratory frame together with the Earth, deviations of the change in the rate of beta decay of radioactive elements single out three directions in the physical space.

EXPERIMENTAL INVESTIGATIONS OF CHANGES IN β-DECAY RATE OF 60Co AND 137Cs

Results of simultaneous measurements of beta-decay rate with the aid of Ge(Li)-detectors performed at two laboratories 140km apart (INR RAS, Troitsk, Co-60, and JINR, Dubna, Cs-137) during a period from 15.03.2000 till 10.04.2000, are presented. Regular deviations of the count rate of gamma-quanta following the beta-decay of

0.2% (JINR, Cs-137) from the statistical average, are observed. The analysis of extremum deviations of gamma-quanta count rate shows that the set of directions of tangents to the Earths parallels of latitude at the extremum points of trajectories of motion in the space of each laboratory clearly forms three separate compact subsets of directions which agree, for two laboratories, to an accuracy of
