Abstract
We have performed a pure optical frequency measurement of the two-photon transitions in atomic hydrogen and deuterium. From a complete analysis taking into account this result and all other precise measurements (by ourselves and other authors), we deduce optimized values for the Rydberg constant, (relative uncertainty of ) and for the and Lamb shifts and [respectively, , and for deuterium]. These are now the most accurate values available.
