Calculation of the two-electron vacuum-polarization corrections to the hyperfine splitting in Li-like bismuth
Abstract
Ab initio calculation of the two-electron vacuum-polarization corrections to the hyperfine splitting in Li-like bismuth is presented. The diagrams with electric and magnetic vacuum-polarization loops are evaluated rigorously to all orders in αZ. The accuracy of the theoretical prediction for the screened quantum electrodynamics contribution to the specific difference of the hyperfine splitting values of H- and Li-like bismuth is improved by a factor of 3.
