Explanation:
In the elastic scattering of a photon through angle a by a free electron initially at rest, the energy E' of the scattered photon is given in terms of the energy E of the incident photon and rest energy of the electron, mc2, by
In the elastic scattering of a photon through angle a by a free electron initially at rest, the energy E' of the scattered photon is given in terms of the energy E of the incident photon and rest energy of the electron, mc2, byE' = E / [ 1 + E/mc2 (1- cos(a)) ].
In the elastic scattering of a photon through angle a by a free electron initially at rest, the energy E' of the scattered photon is given in terms of the energy E of the incident photon and rest energy of the electron, mc2, byE' = E / [ 1 + E/mc2 (1- cos(a)) ].While for optical photons E is much less than mc2 (=0.511 MeV) and energy changes are small, large shifts are predicted for gamma rays of energy E ~ mc2. In this experiment, you will study scattering of a beam of 0.662 MeV gamma rays from a plastic target and detect the scattered radiation using a NaI scintillation detector.
