Assuming incident frequency is above threshold frequency
In: Physics
Only if an electron released by Compton scattering counts as a photoneutron–and they’re considered separate things generally. For the photoelectric effetr, once the threshold is reached to free an electron adding more energy to the photon just give the eletron more kinetic energy. However, once you really crank up the photon energies, Compton scattering becomes more likely. Here the photon knocks loose an electron, but has so much energy that a photon get emitted. If that second photon is above the threshold, it can cause the photoelectric effect.
