Optical Frequency Measurement of the 2S-12D Transitions in Hydrogen and Deuterium: Rydberg Constant and Lamb Shift Determinations
نویسندگان
چکیده
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 16s84d cm21 (relative uncertainty of 7.7 3 10212) and for the 1S and 2S Lamb shifts L1S 8172.837s22d MHz and L2S-2P 1057.8446s29d MHz [respectively, L1S 8183.966s22d MHz, and L2S-2P 1059.2337s29d MHz for deuterium]. These are now the most accurate values available. [S0031-9007(99)09458-2]

High resolution spectroscopy of the hydrogen atom - III. Wavelength comparison and Rydberg constant determination
2014 This paper is the last of a series giving a detailed description of our recent determination of the Rydberg constant. Here we carefully describe the wavelength comparison procedure. The wavelengths of the three two-photon transitions 2S-8D, 2S-10D, and 2S-12D in hydrogen and deuterium are compared to that of an I2-stabilized He-Ne laser which is the present best reference in the optical do...
متن کاملHigh resolution spectroscopy of the hydrogen atom. I. Method and experiment
2014 In order to determine the Rydberg constant R~ to a very high accuracy, we have performed a Doppler-free two-photon absorption experiment on atomic hydrogen and deuterium. We have obtained a new value of R~ which is in excellent agreement with other recent measurements and the most precise one at the present time. Here we give a detailed report on the method and apparatus we have used. A me...
متن کاملTests of Theory in Rydberg States of One-electron Ions
Comparison of optical frequency measurements to predictions of quantum electrodynamics (QED) for Rydberg states of one-electron ions can test theory and allow new determinations of constants of nature to be made. Simplifications in the QED theory of high-angular-momentum states reduces the uncertainty in the prediction of transition frequencies to a level where a new value of the Rydberg consta...
متن کاملThe Lamb Shift of Hydrogen and Low-energy Tests of Qed
Leading logarithmic corrections to the difference of Lamb shifts of s-states EL(1s) − 8EL(2s) and to the life time of 2p1/2 state are considered. The result of Sokolov and Yakovlev for the Lamb splitting of 2s1/2 and 2p1/2 is reevaluated and our new value is 1057.8576(21) MHz. Using value of EL(1s)− 8EL(2s) = -187.237(8) MHz, obtained here, a new value of the Hydrogen and Deuterium ground state...
متن کاملCorrections of Order Α(zα) to Hyperfine Splitting and Lamb Shift
Corrections to hyperfine splitting and Lamb shift of order α(Zα) induced by the diagrams with radiative photon insertions in the electron line are calculated in the Fried-Yennie gauge. These contributions are as large as −7.725(3)α(Zα)/(πn)(mr/m) m and −0.6711(7)α(Zα)/(πn)EF for the Lamb shift and hyperfine splitting, respectively. Phenomenological implications of these results are discussed wi...
