What is the differential cross section for photo-electric effect? Is there a paper that explains this in more detail?
Thanks in advance for any responses!

That one? Which formula?
The photoelectric effect is the phenomenon in which electrons are emitted from a material when it is exposed to light of a certain frequency or higher. This effect was first discovered by Heinrich Hertz in 1887 and later explained by Albert Einstein in 1905.
The scattering differential cross section is a measure of the probability of a photon interacting with a material and being scattered in a specific direction. In the photoelectric effect, this cross section represents the likelihood of a photon being absorbed by the material and causing the emission of an electron.
The intensity of light does not have a significant effect on the photoelectric effect. However, the frequency of light is directly related to the energy of the photons, and only photons with enough energy can cause the emission of electrons in the photoelectric effect. This is known as the threshold frequency.
The photoelectric effect has many practical applications in modern science and technology. It is the basis for the functioning of solar panels, photodiodes, and other light-sensing devices. It also played a crucial role in the development of quantum mechanics and our understanding of the particle-wave duality of light.
The photoelectric effect provides evidence for the particle nature of light, as it shows that light is made up of discrete packets of energy, known as photons. Only photons with enough energy can cause the emission of electrons, and this energy is directly proportional to the frequency of light. This phenomenon cannot be explained by the classical wave theory of light.
