Physics:Araki–Sucher correction
In atomic, molecular and optical physics, the Araki–Sucher correction is a leading-order correction to the energy levels of atoms and molecules due to effects of quantum electrodynamics (QED).[1] It is named after Huzihiro Araki[2] and Joseph Sucher,[3] who first calculated it for the helium atom in 1957. The method is based on a perturbative expansion of the energy in the Bethe–Salpeter equation, and have since been used to calculate corrections for atoms other than helium (e.g. berylium[4] and lithium[5]), and for systems with more than two electrons.[6][7] The correction typically involves the fine-structure constant [math]\displaystyle{ \alpha }[/math] and may sometimes include terms of third order and higher (i.e. [math]\displaystyle{ \sim \alpha^3 }[/math]).
