Abstract

The half-life of ¹²⁸Te relative to the half-life of ¹³⁰Te has been found to be t12128t12130=(1.59±0.05)×10³ by measurement of the ββ-decay products, ¹²⁸Xe and ¹³⁰Xe, in a geologically old (2.4×10⁹ yr) telluride ore. These results yield an upper limit on the lepton nonconservation parameter, η≤0.8×10^-4. RADIOACTIVITY ββ-decay ¹²⁸Te; measured T_1/2=1.5×1024 yr; deduced η≤0.8×10^-4. Detected excess ¹²⁸Xe in old Te ore.
