From Wikipedia, the free encyclopedia

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. beryllium [4] and lithium [5]), and for systems with more than two electrons. [6] [7] The correction typically involves the fine-structure constant and may sometimes include terms of third order and higher (i.e. ).
