Evaluation of the screened vacuum-polarization corrections to the hyperfine splitting of Li-like bismuth
arXiv:1112.3882 · doi:10.1103/PhysRevA.85.022510
Abstract
The rigorous calculation of the vacuum-polarization screening corrections to the hyperfine splitting in Li-like bismuth is presented. The two-electron diagrams with electric and magnetic vacuum-polarization loops are evaluated to all orders in alpha*Z, including the Wichmann-Kroll contributions. This improves the accuracy of the theoretical prediction for the specific difference of the hyperfine splitting values of H- and Li-like bismuth.
