Towards a frequency measurement of the Rydberg constant using the 2S-8S and 2S-8D transitions of hydrogen

A very precise measurement of the Rydberg constant is performed using a direct-frequency comparison of the 2S-8S and 2S-8D two-photon transitions in atomic hydrogen with the difference of two optical standards connected to a frequency chain.< >
