To characterize fast charged particle scattering on an atom, two parameters are introduced, depending on the atom potential and determining the hard scattering (pre-Rutherford asymptotic behavior), and one parameter characterizing multiple scattering in atomic matter from such atoms. It is proven that the latter quantity expresses the screening momentum in the Molière’s multiple Coulomb scattering theory both in the perturbative and semi-classical regimes. For classical scattering on an atom, the existence of a scaling more general than that of Lindhard-Nielsen-Scharff is proven. A relationship between the Molière angle and the radiation length is obtained, taking into account the Coulomb nature of electron scattering on atoms in the next-to-leading logarithmic approximation.
