摘要：

We have measured the amounts of radiogenic Xe-128 and Xe-130 in two, old telluride minerals - krennerite (AuTe2) from Western Australia and altaite (PbTe) from Quebec. We calculated values of (4.2 +/- 0.8) x 10(-4) and (4.4 +/- 0.8) x 10(-4) for the ratio of the total beta-beta-decay half-lives, 130T1/2/128T1/2, from the amounts of radiogenic Xe-130 and Xe-128 in the krennerite and the altaite, respectively. These values are in good agreement with the ratio of half-lives calculated by the quasi-particle random phase approximation for 2-nu-beta-beta-decay.
