Precision Tests of QED in Strong Fields and Nuclear Contributions
1995The most simple of all atoms is hydrogen. One might imagine that its fundamental structure should allow for a theoretical description of the hydrogen spectrum at least as accurate as given by experiment. But as a matter of fact theory could not meet this requirement. E.

Metallic magnetic calorimeters for high precision QED tests at GSI∕FAIR
AIP Conference Proceedings, 2009The quantum electrodynamics belongs to the best tested and established theories in modern physics. However, the evaluation of high order processes, as necessary in the presence of large electric fields, is still demanding. Of particular interest in this field is the Lamb shift of highly charged, hydrogen‐like ions, as the theoretically claimed error ...

Status of Precision QED in Light and Heavy Atoms
1987This paper presents a review of QED in various systems. Precision tests in weakly bound systems are reviewed, tests of radiative corrections in highly ionized atoms and inner shells of neutral heavy atoms are described, and a more speculative application of QED to quarks bound in a cavity is presented.

Precision energy-level measurements and QED of highly charged ions
Canadian Journal of Physics, 2009A review is given of measurements involving the K-shell (np → 1s) transitions of hydrogenlike ions. In many experiments carried out, for example, on electron-beam ion traps and tokamaks, the calculated energies of the Lyman-series lines are utilized as calibration standards for measuring the energies of lines from more complex ions.

High precision calculations and QED effects for two- and three-electron atoms
Physica Scripta, 1993Essentially exact results can now be obtained for the nonrelativistic energy and lowest-order relativistic corrections of helium. A combination of variational calculations and asymptotic expansion methods covers the entire singly-excited spectrum.
