Absolute frequency measurement of the 1S0-3P0 transition of 171Yb with a link to international atomic time

We report the absolute frequency measurement of the unperturbed optical clock transition 1S0-3P0 in 171Yb performed with an optical lattice frequency standard. Traceability to the International System of Units is provided by a link to International Atomic Time. The measurement result is 518 295 836 ...
