The rocket equations for decays of elementary particles
  The decay of elementary particles is described nonrelativistically and using the method of the special theory of relativity. Then the Tsiolkovskii rocket equation is applied to the one photon decay of the excited nucleus of the M\"ossbauer effect. The formation time of photons during decay is supposed nonzero. The Me\v{s}\v{c}erskii equation is possible to identify with the bremsstrahlung equation. All decays described in the ``Review of Particle physics properties'' can be investigated from the viewpoint of the rocket equations
