41 // Class Description:
42 //
43 // Implementation of Coulomb Scattering of a charge particle
44 // on Atomic Nucleus for interval of scattering anles in Lab system
45 // thetaMin - ThetaMax.
46 // The model based on analysis of J.M.Fernandez-Varea et al.
47 // NIM B73(1993)447 originated from G.Wentzel Z.Phys. 40(1927)590 with
48 // screening parameter from H.A.Bethe Phys. Rev. 89 (1953) 1256.
