Photon Interaction Summary

Here's a table highlighting the key information about each interaction:

Name Absorbed/Scattered Proportionality
Rayleigh scattering Scattered \eta \propto Z^2 / E^2
Photoelectric effect Absorbed \tau \propto Z^c / E^3, \; (c=4,5)
Compton scattering Scattered \sigma \propto e^- / g
Pair production Absorbed \kappa_{pair} \propto Z^2 , \; \kappa_{triplet} \propto Z
Photonuclear disintegration Absorbed \sigma_{pn} \propto Z
