//         on base of G4LowEnergyPhotoElectric developed by A.Forti and M.G.Pia
//
// 15 Mar 2010   L. Pandola, removed methods to set explicitly fluorescence cuts.
//               Main cuts from G4ProductionCutsTable are always used
// 30 May 2011   A Mantero & V Ivanchenko Migration to model design for deexcitation
// 22 Oct 2012   A & V Ivanchenko Migration data structure to G4PhysicsVector
