SOME MICROSCOPIC ASPECTS OF RADIATION DAMPING IN NMR

In this paper, several aspects of the quantization of radiation damping in NMR are questioned. A fully quantized theory is given here, as in the case of superradiance in quantum optics. It is shown that a general solution for the density operator of an assembly of N spins can be quite easily found by using only the Pauli matrices algebra and the so-called coherent-state representation.
