Delbrück scattering and the g-factor of a bound electron

Karshenboim Savely G., Milstein Alexander I.

The leading contribution of the light-by-light scattering effects to g-factor of a bound electron is derived. The corresponding amplitude is expressed in terms of low-energy Delbrück scattering of a virtual photon. The result reads Δg = (7/216)α(Zα)5. © 2002 Elsevier Science B.V. All rights reserved.
