Elastic scattering of electrons by cut‐off Coulomb potential U c (r ) is investigated, where U c (r ) = 0, for r > r c and U c (r ) = −1/ r + 1/ r c for r ≦ r c . This is first considered in terms of classical, and later quantum mechanical (partial wave) methods in the low energy range 0 ≦ ϵ ≲ 1/ r c , where ϵ is the energy of the free electron. Scattering in this energy region displays a number of particular characteristics, such as back scattering, at certain energies. It can be concluded that some agreement does exist between the classical and quantum mechanical results.
