Determine the minimum energy e0 of a photon
WebPair production is: When a photon interacts with a nucleus or atom and the energy of the photon is used to create a particle–antiparticle pair. When a photon with enough energy interacts with a nucleus it can produce an electron-positron pair. This means the energy of the photon must be above a certain value to provide the total rest mass ... Webof a photon by a stationary, free electron was studied. In this example, we have E 1 = E ph (the incident photon energy), E 2 = E e0 (the rest energy of the stationary electron, the “target”), E 3 = E ph´ (the energy of the scattered photon), and E 4 = E e´ (the energy
