Absolute frequency measurement of the 1S0 – 3P0 transition of 171Yb

We report the absolute frequency measurement of the unperturbed transition 1S0 -3P0 at 578 nm in 171Yb realized in an optical lattice frequency standard relative to a cryogenic caesium fountain. The measurement result is 518 295 836 590 863.59(31) Hz with a relative standard uncertainty of 5.9×10−16. This value is in agreement with the ytterbium frequency recommended as a secondary representation of the second in the International System of Units.
