1. Tale of two sigmas In class we derived an expression for the Thom- son scattering cross section: 8T representing an effective area (Eqn.(1) is in SI units or m2). Compute the actual value of σ for the electron, ơe, for the proton, ơp and compute a value for the "classical" electron radius. Briefly interpret and discuss the difference of the two σ values.
