Mossbauer experiments in a rotating system: The so-called   "synchronization effect" to explain the extra energy shift between emitted   and absorbed radiation constitutes a complete failure
  We show that a new attempt by C. Corda to once more rehash his so-called "synchronization effect" in order to account for the origin of the extra energy shift between emitted and absorbed radiation in Mossbauer rotor experiments (C. Corda, Int. J. Mod. Phys. D, doi: 10.1142/S0218271819501311) is yet again erroneous, just as were his previous attempts (Ann. Phys. 355, 360 (2015); Ann. Phys. 368, 258 (2016); Int. J. Mod. Phys. D 27, 1847016 (2018)). The correct approach presented herein with regards to the calculation of the energy shift between emitted and absorbed radiation in a rotating system leads to, as a matter of fact, no specific "synchronization effect".
