The rate of radiation damping in magnetic resonance is investigated by solving the Bloch Kirchoff equations, and also by calculating the Rabi nutation rate via the Jaynes-Cummings formalism of quantum optics. It is found that Rabi nutation accounts for the weak early damping only; and it is noted that stimulated emission may contribute to the stronger damping which develops later.
