Graziani, C

The introduction of resonance line width into the QED cyclotron scattering amplitudes is considered. It is shown that the width arises from loop corrections to the electron propagator, which also brings about shifts in the Landau energy levels. A formalism is developed that allows the dressed electron propagator to be derived. It is shown that the Breit-Wigner broadening prescription E[yields]E - i[Gamma]/2 is approximately correct, if the set of solutions of the Dirac equation which diagonalize the mass operator are used as intermediate states.
