Abstract
The results of an experiment measuring the difference Δλ=λa−λ m of the beta-decay constants of atomic and molecular tritium are reported. The difference Δλ is determined by comparing the rates of growth of the relative content of radiogenic helium-3 in samples containing atomic and molecular tritium. The result Δλ=(4.6±0.8)×10−12s−1 corresponds to a relative change of the decay constant by ∼0.26%.
