چکیده

High-precision relativistic atomic structure calculations based on the relativistic many-body perturbation theory and the relativistic configuration-interaction method are shown to provide stringent tests of strong-field quantum electrodynamic (QED) corrections when compared with electron beam ion trap measurements of the spectra of highly-charged, manyelectron ions. It is further shown that theory and experiment are accurate enough to test not just the leading screened QED corrections but also smaller contributions from higher-order Breit interactions, relaxed-core QED corrections, two-loop Lamb shifts, negative-energy state corrections, nuclear polarizations and nuclear recoils.

High precision wavelength measurements of QED-sensitive forbidden transitions in highly charged argon ions.

We present the results of an experimental study of magnetic dipole (M1) transitions in highly charged argon ions (Ar X, Ar XI, Ar XIV, Ar XV) in the visible spectral range using an electron beam ion trap. Their wavelengths were determined with, for highly charged ions, unprecedented accuracy up to the sub-ppm level and compared with theoretical calculations. The QED contributions, calculated in...

QED corrections to the 4p − 4d transition energies of copperlike heavy ions

Quantum electrodynamic (QED) corrections to the 4p−4d transition energies of several copperlike ions with Z = 70 − 92 are calculated non-perturbatively in strong external fields to all orders in binding corrections. Dirac-Kohn-Sham potentials are used to account for screening and corerelaxation effects. For the 4p1/2 − 4d3/2 transition in copperlike bismuth, thorium and uranium, results are in ...

The electronic g-factor in hydrogen-like ions

The precise calculation of the anomaly of the magnetic moment of the elect ron is one of the great successes of QED. According to Dirac theory, the gfactor, which indicates the size of the magnetic moment in multiples of the Bohr magneton eh/ 2 me, should be exactly 2. With QED it is possible to precisely calculate the small deviation from the value 2 which is due to the influence of the cloud ...

Sympathetic cooling of 4He+ ions in a radio-frequency trap.

We have generated Coulomb crystals of ultracold 4He+ ions in a linear radio-frequency trap, by sympathetic cooling via laser-cooled 9Be+. Stable crystals containing up to 150 localized He+ ions at approximately 20 mK were obtained. Ensembles or single ultracold He+ ions open up interesting perspectives for performing precision tests of QED and measurements of nuclear radii. This Letter also ind...
