// Modifications:
// 01.08.06 V.Ivanchenko extend upper limit of table to TeV and review the
//          logic of building - only elements from G4ElementTable
// 08.08.06 V.Ivanchenko build internal table in ekin scale, introduce faclim
// 19.10.06 V.Ivanchenko use inheritance from G4eCoulombScatteringModel
// 09.10.07 V.Ivanchenko reorganized methods, add cut dependence in scattering off e- 
// 09.06.08 V.Ivanchenko SelectIsotope is moved to the base class
//
// Class Description:
//
// Implementation of CoulombScattering of pointlike charge particle 
// on Atomic Nucleus for interval of scattering anles in CM system 
// thetaMin - ThetaMax
//   The model based on analysis of J.M.Fernandez-Varea et al. 
// NIM B73(1993)447 originated from G.Wentzel Z.Phys. 40(1927)590 with 
// screening parameter from H.A.Bethe Phys. Rev. 89 (1953) 1256.
