We studied the resonance fluorescence of Moessbauer radiation of Fe57 nuclei with coherently coupled nuclear sublevels. The obtained results prove that the traditional Moessbauer spectroscopy in scattering geometry is effective enough for experimental investigation of the quantum interference of gamma transitions and for studying the coherencies induced by external radiation fields.

Analytical and numerical calculations describe the effects of shaped radiation pulses on two-level systems in terms of quantum-mechanical scattering. Previous results obtained in the reduced case of amplitude modulation are extended to the general case of simultaneous amplitude and phase modulation. We show that an infinite family of phase- and amplitude-modulated pulses all generate rectangular inversion profiles. Experimental measurements also verify the theoretical analysis.
