Scattering cross-section is a measure of the probability of a particle or wave being scattered by a target object or medium.
Scattering cross-section is calculated by taking the ratio of the scattered flux to the incident flux, and then dividing by the number of scattering particles or molecules in the target.
The size, shape, and composition of the target object or medium, as well as the wavelength and energy of the incident particles or waves, can all affect scattering cross-section.
Scattering cross-section is used to study the properties of particles and materials, such as their size, composition, and interactions with other particles or waves. It is also used in various fields such as atmospheric science, astronomy, and microscopy.
Some common techniques for measuring scattering cross-section include light scattering, X-ray scattering, neutron scattering, and electron scattering. These techniques can be used to measure different aspects of scattering, such as scattering angle, intensity, and polarization.
