Title

Ratio of Double Beta-Decay Rates of 128,130Te

Abstract

We have measured the amounts of radiogenic 128Xe and 130Xe in two, old telluride minerals-krennerite (AuTe2) from Western Australia and altaite (PbTe) from Quebec. We calculated values of (4.2±0.8) × 10-4 and (4.4±0.8) × 10-4 for the ratio of the total ββ-decay half-lives, 130T1 2/128T1 2, from the amounts of radiogenic 130Xe and 128Xe 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 2v ββ-decay.
