## Abstract

We present results of M?ssbauer experiment in a rotating system, whose performance was stimulated by our recent finding (*Phys. Scr.*, 77 (2008) 035302) and which consisted in the fact that a correct processing of K?ndig's experiment data on the subject gives an appreciable deviation of a relative energy shift (Delta E)/E between emission and absorption resonant lines from the standard prediction based on the relativistic dilation of time (that is (Delta E)/E = -v^{2}/(2c^{2}) to the accuracy c^{-2}, where v is the tangential velocity of absorber of resonant radiation, and c is the light velocity in vacuum). Namely, the K?ndig result we have corrected becomes (Delta E)/E = -kv^{2}/(2c^{2}), with k=0.596?0.006 (instead of the result k = 0.5003?0.006, originally reported by K?ndig). In our own experiment we carried out measurements for two absorbers with substantially different isomer shift, which allowed us to make a correction of M?ssbauer data regarding vibrations in the rotor system at various rotational frequencies. As a result we got the overall estimation k = 0.68?0.03.
