We report experimental results of the oscillatory response of a two-level spin system (E'1 centres in glassy silica) excited by a step-modulated radiation tuned to the double-quantum (DQ) resonance. On the basis of a semiclassical calculation of the transient regime, the observed oscillations are ascribed to the nutations of the DQ transitions.

Abstract
We report experimental results of the oscillatory response of a two-level spin system (E'1 centres in glassy silica) excited by a step-modulated radiation tuned to the double-quantum (DQ) resonance. On the basis of a semiclassical calculation of the transient regime, the observed oscillations are ascribed to the nutations of the DQ transitions.File in questo prodotto:
