A monochromatic plane wave scatters from a Lorentz atom where a bound electron obeys the classical equation of motion Assume that the electron displacement and damping are both very small. If r_e = e²/4π ϵ₀mc² is the classical electron radius, show that the integrated total absorption cross section is independent of the damping constant:
