An upper limit for the electron antineutrino mass from the Zurich experiment on tritium β-decay
- 1. Zurich Univ. (Switzerland). Inst. fuer Physik
Description
The endpoint region of the tritium β-spectrum has been measured with 27 eV resolution, using a magnetic spectrometer. The tritium activity was implanted into a thin layer of carbon. The neutrino mass determined is consistent with zero with an upper limit of 18 eV, which includes instrumental and statistical uncertainties as well as uncertainties due to energy loss in the source and to the final electronic states.
