Can Gamma rays produce photoelectric effect?

Best Answers

As long as the energy of the gamma ray photon is greater than the work function of the material on which it is projected, it can produce photoelectric effect. Not only gamma rays, it can even be UV rays or x-rays. read more

Yes. As long as the energy of the gamma ray photon is greater than the work function of the material on which it is projected, it can produce photoelectric effect. Not only gamma rays, it can even be UV rays or x-rays. read more

At small values of gamma ray energy or at high values of gamma ray energy, where the coefficient is proportional to higher powers of the atomic number Z (for photoelectric effect σ f ~ Z 5; for pair production σ p ~ Z 2), the attenuation coefficient μ is not a constant. read more

Gamma ray photons that have been degraded in energy by the process of Compton Scattering subsequently undergo photoelectric absorption. Figure 2. Gamma rays mass attenuation coefficients in lead (Pb), showing the contributions from the photoelectric effect, Compton scattering, and pair production. read more

The photoelectric effect is the most common form of interaction when the energy of the gamma rays is of the same order of magnitude as the energy binding atomic electrons to the nucleus. The gamma ray can then eject an electron away from an atom, sharing its energy between the electron and the excited atom. read more
