This article reviews recent developments in tests of fundamental physics using atoms and
molecules, including the subjects of parity violation, searches for permanent electric dipole …

Recent developments in frequency metrology and optical clocks have been based on
electronic transitions in atoms and singly charged ions as references. The control over all …

1.1. Background This article reports work carried out under the auspices of the Committee
on Data for Science and Technology (CODATA) Task Group on Fundamental Constants. 1 It …

1.1. Background This paper gives the complete 2006 CODATA self-consistent set of
recommended values of the fundamental physical constants and describes in detail the …

We review the progress in atomic structure theory with a focus on superheavy elements and
their predicted ground state configurations important for an element's placement in the …

X-ray spectra following radiative recombination of free electrons with bare uranium ions (U
92+) were measured at the electron cooler of the ESR storage ring. The most intense lines …

Theoretical energy levels of the n= 1 and n= 2 states of hydrogen-like atoms with the nuclear
charge numbers 1≤ Z≤ 110 are tabulated. The tabulation is based on ab initio quantum …

The current status of bound state quantum electrodynamics calculations of transition
energies for few-electron ions is reviewed. Evaluation of one and two body QED correction …

Theoretical calculations of the Lamb shift provide the basis required for the determination of
the Rydberg constant from spectroscopic measurements in hydrogen. The recent high …

Using the SuperEBIT electron beam ion trap, we have measured the 2 s 1/2-2 p 1/2
transitions in U 88+ and U 89+. The measured value of 280.645±0.015 eV for Li-like U 89+ …
