WebFrom the perspective of radiation oncology (i.e. higher energy) physics, here is the main difference, in a few words. Rayleigh scattering is the elastic scattering of a photon off an entire atom. Thomson scattering is the elastic scattering of a photon off a single unbound electron. Both are more likely to happen at lower energies. WebThe coherent (Rayleigh) scattering cross sections in Ref. were calculated from a combination of the Thompson formula and relativistic Hartree-Fock atomic form factors. The photoelectric cross sections were obtained by Scofield [ 14 ] by a phase-shift calculation for a central potential and a Hartree-Slater atomic model.
