Digitization of 93.3-keV recoilless $\gamma$ radiation

We propose a technique for transforming the intensity of quasi-monochromatic recoilless radiation with a photon energy of 93.3 keV, emitted by radioactive Mössbauer sources $^{67}$Ga or $^{67}$Cu, into a sequence of short pulses with individually and independently controlled, on demand, the moments of appearance of pulses, as well as the peak intensity, duration and shape of each pulse. The technique is based on the transmission of recoilless (Mössbauer) 93.3-keV photons from the source through a medium containing resonantly absorbing $^{67}$Zn nuclei. The pulses are formed due to the rapid reciprocating movement of the source relative to the absorber at specified moments in time along the direction of photon propagation at a distance not exceeding half the radiation wavelength. The produced sequences of $\gamma $-ray pulses are similar to the digitization of information carried by electromagnetic waves. They can also be used to develop Mössbauer spectroscopy of the atomic and subatomic structures, as well as open novel opportunities for $\gamma $-ray quantum optics.
