We study the Dirac equation with slowly varying external potentials. Using matrix-valued Wigner functions we prove that the electron follows with high precision the classical orbit and that the spin precesses according to the BMT equation with gyromagnetic ratio g=2. 2000

A relativistic mechanics for a Dirac particle is derived as the semi-classical limit of the Dirac equation. The theory resembles ordinary mechanics, except that some of the phase space variables are four by four matrices. We are able to derive from QED the spin precession equation of Bargmann, Miche
