// 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-

// 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.
