Elaborations on Mössbauer rotor experiments with synchrotron radiation and with usual resonant sources

A comparative analysis of Mössbauer experiments in a rotating system between a recent application using synchrotron radiation [Friedman et al. (2016). Eur. Phys. Lett. 114, 50010; Friedman et al. (2017). J. Synchrotron Rad. 24, 661-666] and usual sources of resonant radiation is carried out. The principal methodological difference between these experiments can be related to the fact that in the former set of experiments the source of the resonant radiation rests in a laboratory frame whereas for the latter set of experiments the source is attached to a rotating system. It is concluded that the utilization of ordinary Mössbauer sources remains the most promising path for further research appertaining to the Mössbauer effect in rotating systems.
