Interactions

Ionization - Excitation Energy transfer to the atom

• Ionization: release of an electron from the atom • Excitation: lift of an electron from an inner shell to one further out

Deexcitation

Energy released by the atom

• Characteristic radiation: the radiation energy is dependent on the electron energy levels (K, L, M etc) and hence characteristic of the given atom • Auger electron
