Hänsch We have measured the frequency of the extremely narrow 1 S -2 S two-photon transition in atomic hydrogen using a remote cesium fountain clock with the help of a 920 km stabilized optical fiber. With an improved detection method we obtain f 1 S -2 S =2466 061 413 187 018 (11) Hz with a relative uncertainty ... [Phys. Rev. Lett. 110, 230801] Published Thu Jun 06, 2013
