Contribution

It introduces a comprehensive relativistic calculation of nuclear recoil effects on the g factor, including one- and two-electron contributions within the 1/Z perturbation framework.

Findings

Recoil effects significantly influence the g factor in high-Z ions.

Relativistic and screening effects are effectively incorporated into the calculations.

Results provide improved theoretical predictions for experimental comparisons.

Abstract

The nuclear recoil effect on the g factor of highly charged Li-like ions is evaluated in the range Z=10-92. The calculations are performed using the 1/Z perturbation theory. The one-electron recoil contribution is evaluated within the fully relativistic approach with the wave functions which account for the screening effects approximately. The two-electron recoil contributions of the first and higher orders in 1/Z are calculated within the Breit approximation using a four-component approach.
