Modulation of mercury-cadmium sensitized fluorescence induced by a rotating magnetic field

Abstract

It is predicted theoretically that mercury-cadmium sensitized fluorescence should be modulated in general, when a rotating magnetic field is applied, and a steady magnetic field perpendicular to the plane of the rotating field. The time dependence of the density matrix, expressed in terms of irreducible tensors, is calculated. The final expression for the intensity of the sensitized fluorescence, as a function of time, is shown to be similar to the corresponding one for resonance fluorescence (both cases referring to 'broad-band' excitation).
