HITRAP: A facility at GSI for highly charged ions
H. -J. Kluge, T. Beier, K. Blaum +20
An overview and status report of the new trapping facility for highly charged ions at the Gesellschaft fuer Schwerionenforschung is presented. The construction of this facility sta…
Spectacular Role of Electron Correlation in the Hyperfine Interactions in States in Alkaline Earth Ions
B. K. Sahoo, C. Sur, T. Beier +3
The low-lying n(=3,4,5)d states alkaline earth ions are of vital importance in a number of different physical applications. The hyperfine structure constants of these s…
Electron Correlation Effects in Hyperfine Interactions in Sc and Y
Bijaya K. Sahoo, Thomas Beier, B. P. Das +2
The relativistic coupled-cluster theory has been employed to calculate the magnetic dipole and electric quadrupole hyperfine structure constants for the stable isotopes Sc a…
Evaluation of the two-photon exchange diagrams for the electron configuration in Li-like ions
A. N. Artemyev, V. M. Shabaev, M. M. Sysak +4
We present ab initio calculations of the complete gauge-invariant set of two-photon exchange graphs for the electron configuration in Li-like ions. These calculat…
Recoil correction to the ground state energy of hydrogenlike atoms
V. M. Shabaev, A. N. Artemyev, T. Beier +3
The recoil correction to the ground state energy of hydrogenlike atoms is calculated to all orders in αZ in the range Z = 1-110. The nuclear size corrections to the recoil effect a…
Exact two-loop vacuum polarization correctionto the Lamb shift in hydrogen-like ions
G. Plunien, T. Beier, G. Soff +1
We present a calculation scheme for the two-loop vacuum polarization correction of order to the Lamb shift of hydrogen-like high-Z atoms. The interaction with the external Co…
