I have been trying to look for a derivation of the Rutherford scattering formula from Hyperphysics, but cannot find one. It doesn't show up in the original paper How is this equation derived? first define the scattering cross-section , and then briefly present the scattering calculations for the Rutherford atom. The remaining sections discuss the measurement techniques and analysis.

An Introduction to Cross Sections 1. Definition of cross section for scattering or reactions Let A = mass number of target (assuming a single pure isotope) If we assume that (a) the probability of interaction depends on the properties of the beam and target particles, and (b) the target is вЂњthinвЂќ, so that only a small fraction of beam particles actually interact, then the following scaling In this equation, s = 2 Ој вЂѕ R N is the normalized path-length, where Ој вЂѕ R is the angular variance of the Rutherford scattering function, N = Пѓ R v i j n j d t is the number of Rutherford scattering events, and Пѓ R is the total cross-section for Rutherford scattering.

If it were not deflected, it will pass the nucleus at distance b .

Rutherford Scattering Formula The scattering of alpha particles from nuclei can be modeled from the Coulomb force and treated as an orbit. The scattering process can be treated statistically in terms of the cross-section for interaction with a nucleus which is considered to be a point charge Ze.
