摘要：

A comparison is made of the probability of thr 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 also analyzed. It is: shown that the probability is systematically lower in geochemical experiments, which characterize the probability of beta beta(2v) decay a few billions years ago. In addition geochemical measurements on young minerals give lower values of T-1/2(Te-130) as compared to measurements on old minerals. It is proposed that this could be due to a change in the weak interaction constant with time. The possibilities of new precise measurements to be performed with the aid of counters and geochemical experiments are discussed, a new geochemical experiment with Mo-100 is proposed.
