考虑了具有非零核自旋的类氢离子g因子的全相对论理论。对原子核的点电荷分布模型和扩展电荷分布模型计算了原子g因子的超精细相互作用修正。同时考虑了磁偶极子相互作用和电四极相互作用。这一修正与QED、核反冲和核大小的修正相结合，得到了具有非零核自旋的类氢离子g因子的理论高精确值。这一结果可用于从g因子实验中精确测定核磁矩。
The fully relativistic theory of the g factor of hydrogenlike ions with nonzero nuclear spin is considered. The hyperfine-interaction correction to the atomic g factor is calculated for both point and extended charge-distribution models for nuclei. Both the magnetic dipole and the electric quadrupole interactions are taken into account. This correction is combined with corrections resulting from QED, nuclear recoil, and nuclear size, to obtain theoretical high-precision values for the g factor of hydrogenlike ions with nonzero nuclear spin. The results can be used for a precise determination of nuclear magnetic moments from g factor experiments.
