Researchers Test High-order QED Effects with Many-electron Highly Charged Ions

Researchers have performed the precision DR spectroscopy measurement with fluorine-like nickel ions by employing the merged-beams method. The measurement builds a bridge which enables comparisons between different theories. The theory of quantum electrodynamics (QED) has achieved great success under weak electromagnetic fields in few-electron quantum systems. QED calculations are sensitive to high-order corrections wi...
