Namely, instead of the relative energy shift Delta E/E = -( 1(0065 +/- 0(011) v(2)/2c(2) reported by Kundig ( v being the linear velocity of absorber and c being the light velocity in vacuum), we derive from his results Delta E/E = -( 1(192 +/- 0.011) v(2)/2c(2). We are inclined to think that the revealed deviation of Delta E/E from relativistic prediction cannot be explained by any instrumental error and thus represents a physical effect. In particular, we assume that the energy shift of the absorption resonant line is induced not only by the standard time dilation effect, but also by some additional effect missed at the moment, and related perhaps to the fact that resonant nuclei in the rotating absorber represent a macroscopic quantum system and cannot be considered as freely moving particles.eninfo:eu-repo/semantics/openAccess[No Keyword Available]ArticleQ2Q2773WOS:000254329000007
