Nuclear Resonant Scattering of Synchrotron Radiation as a Method for Distinction between Covariant Ether Theories and Special Relativity

The paper stresses the importance for basic physics of the new proposed Champeney-like rotor experiment with nuclear resonant scattering of synchrotron radiation. Such an experiment, being sensitive to energy shifts proportional to c −3 (c is the light velocity in vacuum), should be able to distinguish between predictions of special relativity theory and covariant ether theories, and thus allow to differentiate between them. The results of computer simulations of experiments with the 14.4 keV resonance in 57Fe show that an energy resolution ΔE/E at the level of 10−16 can be expected which is enough to reveal the third order term.
