// J. M. Quesada (August 2008).  
// Based  on previous work by V. Lara
//
// Modif (03 September 2008) by J. M. Quesada for external choice of inverse 
// cross section option 
// JMQ (06 September 2008) Also external choice has been added for:
//                      - superimposed Coulomb barrier (if useSICB=true) 
// 20.08.2010 V.Ivanchenko added int Z and A and cleanup; added 
//                        G4ParticleDefinition to constructor, 
//                        inline method to build G4ReactionProduct; 
//                        remove string name
//
