5 Gamma rays
Gamma rays interact with matter in very complicated ways. The three main modes of interaction are –
- Photoelectric effect
- Pair production
- Compton scattering
Compton scattering
Compton scattering is elastic scattering of a photon by an electron.
Momentum and energy are conserved.
All angles of scattering are possible –
[latex]E_2 = \frac{E_1 E_{\epsilon}}{E_1(1-cos \theta) + E_{\epsilon}}[/latex]
Based on the equations for energy conservation and momentum conservation, students should be able to derive the result for [latex]E_2[/latex], as well as other important quantities, such as maximum scattered energy.
