Double Beta Decay of Selenium-82
The half-life for the double beta decay of Se 82 is determined to be (2.76 ± 0.88) 1020 years from an analysis of krypton and selenium in tellurobismuthite from Boliden, Sweden. A redetermination of selenium and krypton in umangite from Harbi, Western Moravia, also indicates a longer half-life for Se 82 than the preliminary value of 1.4 × 10 20 years reported earlier. The amounts of neutron capture products observed in the umangite and tellurobismuthite require a much higher natural neutron flux in these ores than that reported in granites.
