Compton Apps
When a gamma-ray Compton scatters in a material energy is transferred from the incident photon to an electron. The plot below visualises the share of energy as a function of Compton scattering angle.
The angle through which a gamma-ray Compton scatters depends upon its initial energy. The probability of a gamma-ray scattering through a particular angle is determined from the Klein-Nishina formula, visualised below.
