ABSTRACT
The phenomenon of scattering is important in the study of classical systems. But when the size of the systems become so small that we cannot directly see them, or when the forces involved are so short–ranged that we cannot directly measure them, scattering becomes an indispensable probe. In the structural analysis of matter scattering is the primary method of investigation, particularly at high energies. Scattering is also important in the study of transport phenomena such as conductivity, specific heat of bulk matter, because these properties are affected by the scattering of free electrons and phonons inside the material.
