Effects of the nuclear charge distribution upon the total cross-section of dielectronic recombination are investigated. We calculated isotope shifts of resonance energies for H-, He- and Li-like heavy ions in the relativistic domain fromZ= 54 toZ= 94. We point out that the position of the...

The influence of quantum electrodynamic (QED) corrections on the valence electrons in superheavy atoms with nuclear charge Z â‰ˆ112 is studied within the effective local-potential approximation and the self-consistent approach. The results are obtained from a relativistic coupled-cluster...

We present an ab initio calculation of the screened self-energy correction for 1s22p3/2 and 1s22s states of Li-like ions with nuclear charge numbers in the range Z = 12â€“100. The evaluation is carried out to all orders in the nuclear strength parameter ZÎ±. This investigation concludes...

As a result of recent advances in both atomic theory and experiment, The isotope shift method now stands as the method of choice for the determination of nuclear charge radii in light few-electron atoms, and it provides a unique measurement tool for the study of exotic 'halo' nuclei. This paper...

The method and status of a study to provide numerical, high-precision values of the self-energy level shift in hydrogen and hydrogen-like ions is described. Graphs of the self energy in hydrogen-like ions with nuclear charge number between 20 and 110 are given for a large number of states. The...

The search for weak-interaction-induced atomic parity nonconservation, initiated in the 1970s, challenges both theory and experiment. Since the weak interaction is very short range, the atomic effects increase rapidly with nuclear charge, as Z3. The focus has thus been on heavy atoms, where...
