Abstract
We have performed a pure optical frequency measurement of the 2S-12D two-ph oton transitions in atomic hydrogen and deuterium. From a complete analysis taking into account this result and all other precise measurements (by our selves and other authors), we deduce optimized values for the Rydberg const ant, R-infinity = 109737.315 685 16(84) cm(-1) (relative uncertainty of 7.7 x 10(-12)) and for the 1S and 2S Lamb shifts L-1S = 8172.837(22) MHz and L 2S-2P = 1057.8446(29) MHz [respectively, L-1S = 8183.966(22) MHz, and L2S-2 P = 1059.2337(29) MHz for deuterium]. These are now the most accurate value s available.
