Abstract
The beta 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 mass at the 95% confidence level.
