I want to know more about its cross section and its relationship with the scattering angle and energy of photon!Thomson scattering is a phenomenon in which electromagnetic radiation (such as light) is scattered by charged particles, typically electrons, in a material. It is named after physicist J. J. Thomson who first described it in the late 19th century.
Thomson scattering occurs when an electromagnetic wave interacts with an electron, causing the electron to oscillate and emit radiation in all directions. This scattered radiation can then be detected and analyzed to gain information about the material and its properties.
Thomson scattering is commonly used in various fields of science and engineering, such as plasma physics, astrophysics, and materials science. It is also used in diagnostic techniques for studying materials and in remote sensing applications for studying atmospheric conditions.
Thomson scattering is distinct from other types of scattering, such as Raman scattering and Compton scattering, in that it involves the interaction of electromagnetic radiation with free electrons. The scattered radiation in Thomson scattering has the same frequency as the incident radiation, while in other types of scattering the frequency may change.
Thomson scattering can be observed in many natural and man-made processes. Examples include the blue color of the sky (caused by Thomson scattering of sunlight by gas molecules in the Earth's atmosphere) and the aurora borealis (caused by Thomson scattering of solar wind particles by Earth's magnetic field).
