ocw.mit.eduphotoelectron is the most tightly bound or K shell of the atom. • The photoelectron appears with an energy given by E e-= hv – E b (Eb represents the binding energy of the photoelectron in its original shell) Thus for gamma-ray energies of more than a few hundred keV, the photoelectron carries off the majority of the original photon energy.
