//                    (27th November 2001)
//
// PhysicsList program
//
// Modified:
//
// 14-02-03 Fix bugs in msc and hIon instanciation + cut per region
//
// 05-02-05 AH - changes to G4Decay - added is not short lived protection
//          and redefined particles to allow non-static creation
//          i.e. changed construction to G4MesonConstructor, G4BaryonConstructor
// 
// 23-10-09 LP - migrated EM physics from the LowEnergy processes (not supported) to 
//          the new G4Livermore model implementation. Results unchanged.
