Rutherford scattering is derived assuming only one scattering event between incident particles and scatter- ing material. This approximation is valid for large angles, where the frequency of atoms scattering o multiple par-ticles is low relative to the frequency of single scatterers. However, this is not the case for small angles, and in this regime, our Rutherford formula breaks down.
