Relativistic corrections to transition frequencies of Ag I, Dy I, Ho I, Yb II, Yb III, Au I and Hg II and search for variation of the fine structure constant
V. A. Dzuba, V. V. Flambaum
Dependence of transition frequencies on the fine structure constant is calculated for several many-electron systems which are used or planned to be used in the labo…
Relativistic corrections to transition frequencies of Fe I and search for variation of the fine structure constant
V. A. Dzuba, V. V. Flambaum
Relativistic energy shifts of the low energy levels of Fe have been calculated using the Dirac-Hartree-Fock and configuration interaction techniques. The results are to be used in…
Many-body calculations of relativistic energy shifts for single- and double-valence atoms
I. M. Savukov, V. A. Dzuba
Relativistic Hartree-Fock method together with many-body perturbation theory and configuration interaction techniques are used to calculate relativistic energy shifts for frequenci…
Coupled-cluster single-double calculations of the relativistic energy shifts in C IV, Na I, Mg II, Al III, Si IV, Ca II and Zn II
V. A. Dzuba, W. R. Johnson
The relativistic coupled-cluster single-double method is used to calculate the dependence of frequencies of strong -transitions in many monovalent atoms and ions on the fine-st…
An universal algorithm of calculating terms of atomic many-body perturbation theory
V. A. Dzuba
An algorithm, based on numerical description of the terms of many-body perturbation theory (Goldstone diagrams), is presented. The algorithm allows the use of the same piece of com…
Atomic electric dipole moments of He and Yb induced by nuclear Schiff moments
V. A. Dzuba, V. V. Flambaum, J. S. M. Ginges
We have calculated the atomic electric dipole moments (EDMs) d of ^3He and ^{171}Yb induced by their respective nuclear Schiff moments S. Our results are d(He)= 8.3x10^{-5} and d(Y…
