Abstract

We have performed a pure optical frequency measurement of the 2S-12D 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, R= 109 737.315 685 16(84) cm-1(relative uncertainty of 7.7 × 10-12) and for the 1S and 2S Lamb shifts L1S= 8172.837(22) MHz and L2S-2P= 1057.8446(29) MHz [respectively, L1S= 8183.966(22) MHz, and L2S-2P= 1059.2337(29) MHz for deuterium]. These are now the most accurate values available.
