Image of atom

Many physical techniques rely on the interaction between high energy electrons and the atoms in a solid. There are many possible interactions and some of the more useful (in that they give rise to measurable effects) are simulated in Inelastic Scattering.

In the simulations that follow, high energy electrons - typically 20keV or higher - are allowed to interact, one by one, with a single atom of aluminium. This atom is assumed to be part of a solid metallic specimen and contributes three electrons to a valence band or conduction band.
