WebThe Feynman diagram shown in Fig. 13.19 (b) describes Compton scattering in which a photon scatters off a free electron producing a photon and an electron with different momentum and energy. The in-coming and out-going photons in this scattering process are represented by free wavy lines, while the solid line joining the two vertices is referred to … WebDec 12, 2024 · Feynman diagrams are just pictorial representations of terms in a perturbation series. EM fields interact with the electron field, always. The diagrams for Compton scattering focus on those interactions which contribute to the desired amplitude which is defined by initial and final states.
