On the theory of coherent ultrasonic modulation of Mössbauer gamma-radiation

Abstract
A unified and relatively simple method is proposed for theoretically describing the transmission of Mössbauer gamma-quanta, irradiated by a coherently rf vibrating source and emerging through a system consisting of n (0 ≤ n < ∞) resonant absorbers, coherently vibrating with different frequencies, phases and amplitudes. General results for the spectral distribution and for the full intensity of the radiation are derived, reproducing particular results obtained up to now. These considerations are based on classical dispersion theory
