A Mössbauer experiment in a rotating system on the second-order Doppler shift: confirmation of the corrected result by Kündig

Abstract

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

Interpretation of Mössbauer experiment in a rotating system: A new proof for general relativity

“…The results have shown that previous analyses missed an important effect of clock synchronization and that the correct general relativistic prevision gives k ≃ 2 3 in perfect agreement with the new experimental results in [2]. Thus, the general relativistic interpretation in this letter shows that the new experimental results of the Mössbauer rotor experiment are a new, strong and independent proof of Einstein general relativity.…”

“…In other words, its theoretical absence in the works [1]- [8], [11]- [13] reflected the incorrect comparison of clock rates between a clock at the origin and one at the detector [15]. This generated wrong claims of invalidity of relativity theory and/or some attempts to explain the experimental results through "exotic" effects [1,2,11,12,13] which, instead, must be rejected.…”

“…In a couple of recent papers [1,2], the authors first re-anayzed in [1] the data of a known experiment of Kündig on the transverse Doppler shift in a rotating system measured with the Mössbauer effect [3], and second, they carried out their own experiment on the time dilation effect in a rotating system [2]. In [1] they found that the original experiment by Kündig [3] contained errors in the data processing.…”

“…The authors of [1] have also shown that the experiment [8], which contains much more data than the ones in [4][5][6][7], also confirms the supposition k > 0.5. Motived by their results in [1] the authors carried out their own experiment [2]. They decided to repeat neither the scheme of the Kündig experiment [3] nor the schemes of other known experiments on the subject previously mentioned above [4][5][6][7][8].…”

Clock hypothesis of relativity theory, maximal acceleration, and Mössbauer spectroscopy

“…[18] occurred and that the value for b should be recalculated to give the corrected result, b cor = 1.19 ± 0.03, which substantially disagrees with SRT. The same experimenters repeated a similar experiment [21] and found b = 1.32 ± 0.06, again in serious disagreement with SRT.…”
