Detailed Description

Special class providing particle energy loss fluctuations in Si material (Landau fluctuations).

The main method simply follows the strategy taken in Geant4 class G4UniversalFluctuation by V. Ivanchenko. As the fluctuation is strongly dependent on particle type and it's energy, detailed calculations of mean ionisation losses have been implemented as well. The differ for hadrons (follows Geant4 class G4BetheBlochModel), muons (follows Geant4 class G4MuBetheBlochModel) and electrons & positrons (follows Geant4 class G4MollerBhabhaModel) ... All the details about physics used can be found in http://cern.ch/geant4/UserDocumentation/UsersGuides/PhysicsReferenceManual/fo/PhysicsReferenceManual.pdf
