// Author: Luciano Pandola
//         on base of G4LowEnergyIonisation developed by A.Forti and V.Ivanchenko
//
// History:
// -----------
// 12 Jan 2009   L. Pandola   1st implementation. Migration from EM process 
//                            to EM model. Physics is unchanged.
// 23 Oct 2009   L. Pandola   remove un-necessary methods to manage atomic 
//                            deexcitation (done by G4VEmModel)
// 01 Jun 2011   V Ivanchenko general cleanup - all old deexcitation code removed
// 04 Jul 2011   L Pandola    removed unused private member
