Los Alamos free molecular and atomic tritium beta decay experiment
Description
An initial measurement of the tritium beta spectrum spanning an energy range of 16.4 - 18.9 keV has been performed using a free molecular tritium gas source. With the data from this preliminary low statistics measurement (approx.72 hours of data), we are able to set an upper limit on the electron-antineutrino mass of 36 eV at the 95% confidence level. Measurements with a gaseous source eliminate many of the ambiguities arising from uncertainties associated with solid-source-based measurements. The ultimate neutrino mass sensitivity of our system should be about 10 eV or less. 13 refs., 9 figs
