Compton scattering - Wikipedia

WebAbsorption of Radiation by Atoms and Molecules, part a 0 points possible (ungraded) Electromagnetic radiation (photons) can be absorbed by atoms and molecules if the energy of the incoming photon is equal to the energy associated with transitions in energy levels of the atoms or molecules. An incoming photon in this stream collides with a valence electron in the graphite target. In the course of this collision, the incoming photon transfers some part of its energy and momentum to the target electron and leaves the scene as a scattered photon. grants handbook legal aid
