Abstract: A frequency measurement of the fine-structure transition 3P1–3P0, Δmj=0 in the first metastable triplet of 24Mg is reported. The experiment has been performed on a metastable atomic beam interacting with the submillimetric radiation (λ≅0.5 mm) of a phase-locked backward wave oscillator. The transition is observed via the fluorescence emission at 4571 Å of the intercombination line 3P1–1S0. The center frequency was evaluated to be ν=601277.16±0.05 MHz with precision limited by first-order Doppler effect.
