Overview of Compton scattering and Rayleigh scattering

When the incoming X-rays are not incident, they are scattered to produce fluorescence, but are caused by atoms that “collide” with the sampleA change in the direction of particle motion. In Compton scattering, X-rays hit a sample of electrons. Since some of the energy is transferred to the electron when it collides, the X-rays leave the collision with less energy. Is that why we see a lower energy at Compton Peak

Greater than the source excitation energy. In Rayleigh scattering, electromagnetic radiation is dispersed by a particle with a radius less than about 1/10 of the wavelength of radiation.

Overview of Compton scattering and Rayleigh scattering

In Rayleigh scattering, photons are scattered by tightly bound electrons in which the atoms are neither ionized nor excited. Incident photons are scattered with (essentially) constant energy. Rayleigh scattering occurs mostly at low energies and high subweights.
