Abstract

The Geant4 simulation toolkit encompasses the low energy electromagnetic package, implementing a precise treatment of electromagnetic interactions of particles with matter down to energies of a few hundred eV. This package includes a component handling the process of atomic relaxation; it models the de-excitation of an atom left in an excited state by the creation of a vacancy originated by a primary, and the emission of X-ray fluorescence and Auger electrons. The design of the package and the physics models implemented are presented.
