| Résumé | (disponible en anglais seulement)
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 ßß-decay half-lives, T12 128/T12 130 , from the amounts of radiogenic 128Xe
and 130Xe in the melonite and the altaite, respectively, and a value of T12 128=(1.8+/-0.7)*1024y. Lepton number violation is not required by these results. |
