This paper gives the 1998 self-consistent set of values of the basic constants and conversion
factors of physics and chemistry recommended by the Committee on Data for Science and …

The present status and recent developments in the theory of light hydrogenic atoms,
electronic and muonic, are extensively reviewed. The discussion is based on the quantum …

This paper gives the 2002 self-consistent set of values of the basic constants and conversion
factors of physics and chemistry recommended by the Committee on Data for Science and …

Quantum electrodynamics (QED) is the first successful and still the most successful quantum
field theory. Simple atoms, being essentially QED systems, allow highly accurate theoretical …

The comparison of theory and experiment for energy levels of strongly bound electrons
provides a critical test of quantum electrodynamics in strong fields. A theoretical evaluation …

We have derived the complete formula for the α 7 m contribution to energy levels of an
arbitrary triplet state of the helium atom, performed numerical calculations for the 2 3 S and 2 …

In this work we report state-of-the-art theoretical calculations of the dipole polarizability of the
argon atom. Frequency dependence of the polarizability is taken into account by means of …

This review is focused on the borderline region of theoretical physics and mathematics. First,
we describe numerical methods for the acceleration of the convergence of series. These …

High-precision variational calculations for the rovibrational states in the range of the total
orbital momentum L= 0–4 and vibrational quantum number v= 0–4 for the H 2+ and HD+ …

We have measured the combination of hydrogen Lamb shifts L 1 S− 5 L 2 S+ 4 L 4 P by
comparing the frequencies of the 1 S− 2 S and 2 S− 4 P transitions. The measurement …
