Chapter 4Particle scattering

The interaction of fast charged particles with matter provides the basic physical mechanism underlying most applications of charged particle beam instruments. In this interaction, an incident particle strikes a target, transfering momentum and energy. The incident particle is completely characterized by its rest mass, charge, momentum, and spin polarization. The target can consist of bulk material (solid, liquid, or vapor), a single atom, a molecule, or a second particle (composite or pointlike). The interaction can be governed by the strong, weak, Coulomb, or gravitational forces. The gravitational force is too weak to be important for charged particles on the laboratory scale of dimensions. However the classical ...
