Abstract
We have constructed a frequency synthesis chain in order to compare the 1s2s Hydrogen transition (Lyman-(alpha) , 2466 THz) with the Methane stabilized He-Ne-laser at 88,4 THz. Phaselocks for all transfer oscillators have been established. The 88 THz line serves as a secondary frequency standard, currently operating at an absolute reproducibility of 2 X 10-12 and a stability of 10-13 at 10 - 100 s integration time. We report on the transfer of this precision to the Lyman-(alpha) frequency of the hydrogen atom, which yields an improved value of the Rydberg constant.
