//      Author:        Maria Grazia Pia   (pia@genova.infn.it)
// 
//      Creation date: 23 October 1998
//
//      Modifications: 
//
//        8 March 2002,  Fan Lei (flei@space.qinetiq.com)
//              added 
//              1) SetRDM () to switch on/off IC process
//              2) GetOrbitNumber () to return the CE oribit number
//              3) GetBondEnergy() for the converted e-
//              4) IsaGamma() to separate CE from gamma
//
//        21 Nov. 2001, Fan Lei (flei@space.qinetiq.com)
//              i) added G4int _nucleusZ initialise it through the constructor
//              ii) modified SelectGamma() to allow the generation of conversion electrons      
//              iii) added #include G4AtomicShells.hh
//      
//        15 April 1999, Alessandro Brunengo (Alessandro.Brunengo@ge.infn.it)
//              Added creation time evaluation for products of evaporation
