The Half-life of 130Te Double ^-decay
In order to determine the half-life of the 130Te double /?-decay, the amounts and isotopic composition of xenon extracted from tellurium ores, from the Oya gold mine in Japan, have been measured with a high-sensitivity mass spectrometer. Compared with atmospheric xenon an excess was definitely found at mass numbers 129, 130 and 131 in the extracted xenon. The excess of 130Xe is predominant, the...
متن کامل(recommended) Half-life Values for Two Neutrino Double Beta Decay
All existing ”positive” results on two neutrino double beta decay in different nuclei were analyzed. Using procedure recommended by Particle Data Group weighted average values for half-lives of Ca, Ge, Se, Zr, Mo, Mo Ru (0+1 ), Cd, Nd and U were obtained. Existing geochemical data were analyzed and recommended values for half-lives of Te and Te are proposed. We recommend to use these results as...
متن کامل– 1 – Neutrinoless Double - Β Decay
Neutrinoless double-beta (0νββ) decay would signal violation of total lepton number conservation. The process can be mediated by an exchange of a light Majorana neutrino, or by an exchange of other particles. However, the existence of 0νββ decay requires Majorana neutrino mass, no matter what the actual mechanism is. As long as only a limit on the lifetime is available, limits on the effective ...
متن کاملNeutrinoless Double Β-decay 1
The neutrinoless double β-decay is reviewed. Model independent evidence in favor of neutrino masses and mixing is briefly summarized. The data of the recent experiments on the search for 0νββ-decay are presented and some future experiments are discussed. The possible values of the effective Majorana mass, which can be predicted on the basis of the neutrino oscillation data under different assum...
