Loop-after-loop contribution to the second-order Lamb shift in hydrogenlike low-Z atoms
We present a numerical evaluation of the loop-after-loop contribution to the second-order self-energy for the ground state of hydrogenlike atoms with low nuclear charge numbers Z. The calculation is carried out in the Fried-Yennie gauge and without an expansion in Zα. Our calculation confirms the results of Mallampalli and Sapirstein and disagrees with the calculation by Goidenko and coworkers....
متن کاملSixth-Order Vacuum-Polarization Contribution to the Lamb Shift of the Muonic Hydrogen
The sixth-order electron-loop vacuum-polarization contribution to the 2P1/2 − 2S1/2 Lamb shift of the muonic hydrogen (μ−p+ bound state) has been evaluated numerically. Our result is 0.005295 (1) meV. This eliminates the largest uncertainty in the theoretical calculation. Combined with the proposed precision measurement of the Lamb shift it will lead to a very precise determination of the proto...
متن کاملVacuum polarization in muonic atoms: the Lamb shift at low and medium Z
In muonic atoms the Uehling potential (an effect of a free electronic vacuum polarization loop) is responsible for the leading contribution to the Lamb shift causing the splitting of states with ∆n = 0 and ∆l 6= 0. Here we consider the Lamb shift in the leading nonrelativistic approximation, i.e., within an approach based on a certain Schrödinger equation. That is valid for low and medium Z as ...
متن کاملHadronic Vacuum Polarization and the Lamb Shift
Recent improvements in the determination of the running of the fine-structure constant also allow an update of the hadronic vacuum-polarization contribution to the Lamb shift. We find a shift of −3.40(7) kHz to the 1S level of hydrogen. We also comment on the contribution of this effect to the determination by elastic electron scattering of the r.m.s. radii of nuclei.
متن کاملNew Polarization Operator Contributions to Lamb Shift and Hyperfine Splitting
We calculate radiative corrections to the Lamb shift of order α3(Zα)5m and radiative corrections to hyperfine splitting of order α(Zα)EF generated by the diagrams with insertions of radiative photons and electron polarization loops in the graphs with two external photons. We also obtain the radiativerecoil correction to hyperfine splitting in muonium generated by the diagrams with the τ polariz...
