High-Resolution Frequency Measurement of the 3P1-3P0 24Mg Transition
A Godone1, E Bava1 and C Novero2
Show affiliationsAdvances towards the realization of an absolute frequency standard in the submillimetre region are reported. The 3P1 
3P0, Δmj = 0 fine-structure transition in the metastable triplet of 24Mg has been observed in an atomic beam with a Ramsey-type interrogation technique. Its frequency, measured with an accuracy of ± 3 × 10-11 with respect to a Cs standard, turned out to be ν0 = (601 277 157 860 ± 20) Hz.
