摘要：

Tellurobismuthite (Bi2Te3) has been analyzed for Xe isotopes to determine the half-life for double-beta decay of Te-130. Excess Xe-130 amounts to (6.18+/-0.18)x10(7) atom/g with 47.8 wt. % Te, or (1.24+/-0.04)x10(13) for the parent/daughter ratio Te-130/Xe-130. With (9.3+/-1.1)x10(7) yr for the Xe retention age of Te mineral, this provides (7.9+/-1.0)x10(20) yr for the absolute half-life of Te-130 double-beta decay. With this and a literature ratio T-1/2(130)/T-1/2(128) of (3.53+/-0.11)x10(-4), we have (2.2+/-0.3)x10(24) yr for the absolute half-life of Te-128 double-beta decay.
