The 2s 1/2 –2p 1/2 Lamb Shift in He
نویسنده
چکیده
The current theoretical status of the Lamb shift in He is discussed. Recent calculations of twoloop binding corrections to the Lamb shift significantly shift the theoretical value of the “classic” Lamb shift in He, i.e. of the 2S1/2–2P1/2-interval. In this brief research note, we present a new (theoretical) value for this interval which reads 14041.474(42) Mhz. The theoretical uncertainty is reduced as well as the discrepancy between theory and experiment. Planned measurements should be of help in further elucidating the situation.

The maximal acceleration corrections to the Lamb shift of one– electron atoms are calculated in a non–relativistic approximation. They are compatible with experimental results, are in particularly good agreement with the 2S − 2P Lamb shift in hydrogen and reduce by ∼ 50% the experiment-theory discrepancy for the 2S − 2P shift in He. PACS: 04.90.+e, 12.20.Ds.

The proton structure and proton polarizability corrections to the Lamb shift of electronic hydrogen and muonic hydrogen were evaluated on the basis of modern experimental data on deep inelastic structure functions. Numerical value of proton polarizability contribution to (2P-2S) Lamb shift is equal to 4.4 GHz.
متن کاملThe Lamb Shift Experiment in Muonic Hydrogen
The subject of this thesis is the muonic hydrogen (μ−p) Lamb shift experiment being performed at the Paul Scherrer Institute, Switzerland. Its goal is to measure the 2S − 2P energy difference in μp atoms by laser spectroscopy and to deduce the proton root–mean– square (rms) charge radius rp with 10 −3 precision, an order of magnitude better than presently known. This would make it possible to t...
متن کاملOptical Frequency Measurement of the 2S-12D Transitions in Hydrogen and Deuterium: Rydberg Constant and Lamb Shift Determinations
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...
