The g factors of bound particles in quantum electrodynamics

Abstract
A quasipotential method is formulated for calculating relativistic and radiative corrections to the magnetic moment of a two-particle bound state in the case of particles of arbitrary spin. It is shown that expressions for the g factors of bound particles contain terms of order O2) that depend on the spin of particles. Numerical values of the g factor of an electron in the hydrogen and deuterium atoms are obtained.
