//  J. M. Quesada (August 2008).  
//  Based  on previous work by V. Lara
//
// Modified:
// 03.09.2008 by J. M. Quesada for external choice of inverse 
//                    cross section option (default OPTxs=2)
// 06.09.2008 by JMQ Also external choice has been added for
//     superimposed Coulomb barrier (if useSICB=true, default false) 
// 20.08.2010 V.Ivanchenko added int Z and A and cleanup; added 
//                        G4ParticleDefinition to constructor
