Abstract:
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. (C) 2002 Elsevier Science B2002 Elsevier Science B.V.
