High precision hyperfine measurements in Bismuth challenge bound-state strong-field QED

High precision hyperfine measurements in Bismuth challenge bound-state strong-field QED

Precision measurements provide a sensitive test of fundamental constants and their uncertainties. Here the authors precisely measure the hyperfine structure splitting in bismuth ions, and report significant discrepancy with the theoretical prediction of quantum electrodynamics.
