Interacción de la radiación con la materia

Rayleigh Scattering Let us now consider the scattering of electromagnetic radiation by neutral atoms. For instance, consider a hydrogen atom. The atom consists of a light electron and a massive proton. As we have seen, the electron scatters radiation much more strongly than the proton, so let us concentrate on the response of the electron to an incident electromagnetic wave. Suppose that the wave electric field is again polarized in the z -direction. We can approximate the electron's equation of motion as There are two features of Rayleigh scattering which are worth noting. First of all, it is much weaker than Thompson scattering (since  <<0 ). Secondly, unlike Thompson scattering, it is highly frequency dependent.

Thompson scattering Consider a plane electromagnetic wave of angular frequency interacting with a free electron of mass and charge . Suppose that the wave is polarized such that its associated electric field is parallel to the z - axis:
