摘要：

A comparison is made of the probability of the process of two-neutrino double beta decay for Se-82 and Zr-96 in direct (counter) and geochemical experiments. The experimental data for Te-130 are analyzed. It is shown that this probability is systematically lower in geochemical experiments, which characterize the probability of 2 beta(2 nu) decay 10(9) yr ago. It is proposed that this could be due to a change in the weak-interaction constant with time. It is proposed that a series of new, precise measurements be performed with the aid of counters and geochemical experiments. (C) 1998 American Institute of Physics.
