//      Author:        Maria Grazia Pia (pia@genova.infn.it)
//
//      Creation date: 23 October 1998

//      Modifications:
//          
//        15 April 1999, Alessandro Brunengo (Alessandro.Brunengo@ge.infn.it)
//              Added creation time evaluation for products of evaporation
//
//        21 Nov 2001, Fan Lei (flei@space.qinetiq.com)
//           Modified GenerateGamma() and UpdateUncleus() for implementation
//           of Internal Conversion processs
// 
//        8 March 2002, Fan Lei (flei@space.qinetiq.com)
//          Added  SetEO () , GetEO(), UpdateElectrons() to allow the assignment 
//          and modification of electron configuration.
//
//        18 October 2002, F. Lei
//          Added GetVaccantSN() and _vSN in order to link to ARM in low-e em
//          _vSN is updated in UpdateElectron()
//          Added SetVaccantSN(). It is need to to re-set _vSN after each 
//          IC happened.
