Abstract

The relativistic Breit Hamiltonian between electrons is transformed into an effective vector potential \bf A_i for the i.th electron, \bf A_i having the structure of a recoil--corrected hyperfine operator. Apart from a small three--body operator, the Dirac--Breit equation is now easier applied to relativistic magnetic properties of complex systems.
