Rutherford scattering

"Rutherford scattering" is a phenomenon where a charged particle is scattered by Coulomb force of an atomic nucleus. The intensity of this scattering is proportional to the square of the atomic number Z and to (sinθ/2)^-4, where θ expresses the scattering angle. In the case of the electron beam, the scattering approaches to Rutherford scattering at high-angles where scattering caused by the electron cloud around the atomic nucleus can be neglected.
