Abstract
In this paper we calculate the frequency shift induced on a photon by the interaction with a low density electronic plasma. The technique is the standard perturbation theory of quantum electrodynamics, taking i nto account the many body character of the plasma. The shift in the no nrelativistic approximation is shown to be blue. Besides the quantum s hift, the known classical effects and the correct temperature dependen ce are also obtained. Finally the limits of the approximations used ar e discussed.
