Abstract
The interelectronic-interaction corrections of the second order in 1/Z to t he ground-state hyperfine splitting in lithiumlike ions are evaluated. The calculations are performed by using the relativistic configuration-interact ion method and perturbation theory. In addition, the nuclear magnetization distribution effect on the interelectronic-interaction correction of the fi rst order in 1/Z is evaluated within the single-particle nuclear model. The calculations provide an improvement in the theoretical predictions for the hyperfine splitting in lithiumlike ions.
