Title

Double Beta-Decay of Tellurium-128 and Tellurium-130

Abstract

The isotopic composition of xenon has been determined in the gas released by stepwise heating of two, geologically-old tellurium minerals - melonite, NiTe2, from the Robb-Montbray property in Quebec and altaite, PbTe, from the Mattagami Lake area of Quebec. We calculate values of 2540 ± 680 and 2550 ± 1300 for the ratio of the ββ-decay half-lives, T1 2 128/T1 2 130, from the amounts of radiogenic 128Xe and 130Xe in the melonite and the altaite, respectively, and a value of T1 2 128 = (1.8 ± 0.7) × 1024y. Lepton number violation is not required by these results.
