The above model does not include damping processes and therefore the response described by Equation (???) becomes infinite whenever the frequency of the incident radiation becomes equal to one of the resonant frequencies, ω n . In any actual atomic system the response of the electrons is limited by a number of energy loss mechanisms, including the energy radiated…
