Maximal Acceleration Corrections to the Lamb Shift of Muonic Hydrogen
The maximal acceleration corrections to the Lamb shift of muonic hydrogen are calculated by using the relativistic Dirac wave functions. The correction for the 2S − 2P transition is ∼ 0.38 meV and is higher than the accuracy of present QED calculations and of the expected accuracy of experiments in preparation.

متن کاملLogarithmic two-loop corrections to the Lamb shift in hydrogen
Higher order (α/π)2 (Z α)6 logarithmic corrections to the hydrogen Lamb shift are calculated. The results obtained show the two-loop contribution has a very peculiar behavior, and significantly alter the theoretical predictions for low lying S-states.

متن کاملHigher-order binding corrections to the Lamb shift of 2P states.
We present an improved calculation of higher order corrections to the oneloop self energy of 2P states in hydrogen-like systems with small nuclear charge Z. The method is based on a division of the integration with respect to the photon energy into a high and a low energy part. The high energy part is calculated by an expansion of the electron propagator in powers of the Coulomb field. The low ...
متن کامل0 Higher - order binding corrections to the Lamb shift of 2 P states
We present an improved calculation of higher order corrections to the one-loop self energy of 2P states in hydrogen-like systems with small nuclear charge Z. The method is based on a division of the integration with respect to the photon energy into a high and a low energy part. The high energy part is calculated by an expansion of the electron propagator in powers of the Coulomb field. The low...
متن کاملMaximal Acceleration Corrections to the Lamb Shift of Hydrogen , Deuterium and He +
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.
