Özet

OpenAlex · İngilizce

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 Δ E / E between emission and absorption resonant lines from the standard prediction based on the relativistic dilation of time (that is, Δ E / E =− v 2 /2 c 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 Δ 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.
