Question

Compton scattering is an inelastic scattering of a photon with a charged particles. As a result of such a scattering wavelength increases and energy decreases. Relation between initial wavelength A and final wavelength X is Lambda' - Lambda = h/m_eC(1-cos theta),theta is angle of scattering. Linear attenuation co-efficient/*, is the fraction of xrays or gamma rays absorbed/scattered. Buildup factor B is the ratio of total number of photons arriving at a point to number of photons arriving at that point without being scattered, I = I_0 Be^-Mut

Explanation / Answer

The Compton equation tells us that the wavelength shift (D lambda =lambda '-lambda ) is independent of the original wavelength. Therefore the fractional wavelength shift is inversely proportional to lambda .

Compton scattering can be used as an analytical tool for examining the electronic structure of a solid.

The results of Compton scattering experiments provide further evidence for the particle nature of electromagnetic radiation, as required by a quantum description of interaction of the radiation with electrons.

Compton scattering is of prime importance to radiobiology, as it is the most probable interaction of gamma rays and high energy X-rays with atoms in living beings and is applied in radiation therapy.

If we allow a monochromatic beam of x-rays to fall on a solid specimen such as graphite , x-rays are scattered from both the atomic nuclei and the surrounding electrons in the specimen.

lambda ' - lambda = (h/mc) (1 - cos (theta) )
