Popis:	Measurements of the tritium s-spectrum are reported. Thin sources consisting of a monolayer of tritiated hydrocarbon molecules were used. No indication of a nonzero mass mν of the electron antineutrino was found. The result is m2ν=−24 ± 48 ± 61 eV2 (1σ). An upper limit mν < 11 eV (95% confidence level) is derived.
