ABSTRACT
In Thomson scattering, a free electron oscillates in response to the electric vector of an electromagnetic wave. This type of scattering is important at low energies. The oscillating electron emits a radiation with the same frequency as the incident wave. No energy loss occurs in this process. Only the angle of de±ection is changed in the collision. Quantum mechanics proves Thomson scattering is an extremity of Compton scattering when incident photon energy is brought to zero.
