Elastic Scattering

Elastic scattering of gammas can involve Rayleigh, nuclear Thomson and Delbrück scattering. The Rayleigh process in Geant4 can be simulated with either the Penelope (Penelope Models) or Livermore models (Low Energy Livermore Model). A more detailed model involving atomic and molecular interactions is included as a JAEA model (JAEA Elastic Scattering Model). These specific implementations are described in more detail below.
