Clean-up?
editThe note says that the article needs clean-up, but it looks fine to me. It's short and to the point; why should it need more? Geoffrey.landis 15:51, 7 May 2007 (UTC)
I removed the clean-up tag because that referred to a previous version of the article. Shinigami27 17:41, 29 October 2007 (UTC)
Equation
editI'd be willing to add the equation for the impact parameter but i tried for a while and i am lacking in the editing skills. if someone wants to help me or just figure it out from this b=z1z2e^2 over 8piE0K times cot (theta/2)where b= impact parameter, z1 z2 are the atomic masses of the scattering particle and target, e is the electric charge of an electron, E0 is permittivity of free space, and K is the kinetic energy of the scattering particle. --Vegeta206 03:29, 11 October 2007 (UTC)
