Abstract
The problem of the free induction decay of a two-level spin system in the presence of a strong coupling between a resonant circuit and the system is discussed under different experimental conditions. It is shown that under certain conditions the shapes of these signals are profoundly modifled by this coupling. In some cases one obtains, after a pulse excitation of the system, several emission peaks of energy from the spin system having a population difference below inversion, creating some sort of “photon-bottleneck” or of “coherent echo”.
