摘要
The paper presents a semiclassical treatment of the nuclear magnetization vector m evolution of an initially negatively polarized nuclear spin system into a superradiant (SR) state in the case when m interacts with an LC-circuit, possessing a ringing time much smaller than the radiation damping time. This case corresponds to the pure SR case, when the SR-pulse is not accompanied by stimulated emission. The delay time of the SR-pulse, which is to be observed in the radio frequency range, is conditioned by Nyquist noise. The parameters of SR-pulses are calculated, assuming that the LC-circuit is tuned into the central frequency of an inhomogeneously broadened NMR line. The evaluations are adduced for the spin system of protons in propanediol.
