TYPES OF PHOTON INTERACTIONS

TYPES OF INTERACTIONS
Photons can interact with matter via the following interactions, depending on their energy E. From E low => E high

1. Elastic (Rayleigh) scattering.

2. Photoelectric absorption ( probability: Z 3 / E 3 ).

3. Compton scatter.

4. Pair production.

Photoelectric absorption and Compton scattering are the most important types of interaction.
