Limit on antiνe mass from free molecular tritium β decay
- 1. Los Alamos National Lab., NM (USA)
Description
The β spectrum of free molecular tritium has been measured in order to search for a finite electron antineutrino mass. The final-state effects in molecular tritium are accurately known and the data thus yield an essentially model-independent upper limit of 27 eV on the νe mass at the 95% confidence level. This limit is dominated by the statistics obtained in the data sets. Optimization of the experimental apparatus is underway and an ultimate sensitivity of 10 eV is expected
