本文系统地研究了单电子和少电子重离子的核极化效应。在1/Z的零级和一级核极化修正的结合能，超精细分裂，和束缚电子g因子的评估。结果表明，核极化贡献可以与刚性核修正同时被基本抵消。这为探测强电磁场中的QED效应和确定基本常数提供了新的前景。
A systematic investigation of the nuclear polarization effects in one- and few-electron heavy ions is presented. The nuclear polarization corrections in the zeroth and first orders in 1/Z are evaluated to the binding energies, the hyperfine splitting, and the bound-electron g factor. It is shown that the nuclear polarization contributions can be substantially canceled simultaneously with the rigid nuclear corrections. This allows for new prospects for probing the QED effects in a strong electromagnetic field and the determination of fundamental constants.
