In 1937, Ives performed a detailed analysis of the spectral shifts to be expected of particle beams observed at different angles following a "test theory" which was consistent with the Michelson-Morley experiment (MMX) and the Kennedy-Thorndike experiment (KTX), but which differed from special relativity (and the mathematically equivalent theory of Lorentz and Lamor) in including a parameter ...
This was achieved by Ives–Stilwell who measured α. So β can be determined using Kennedy–Thorndike, and subsequently δ using Michelson–Morley. In addition to those second order tests, Mansouri and Sexl described some experiments measuring first order effects in v / c (such as Rømer's determination of the speed of light ) as being ...
The transverse Doppler effect and consequently time dilation was directly observed for the first time in the Ives–Stilwell experiment (1938). In modern Ives-Stilwell experiments in heavy ion storage rings using saturated spectroscopy, the maximum measured deviation of time dilation from the relativistic prediction has been limited to ≤ 10 −8.
Results of the Frisch–Smith experiment. Curves computed for M N e w t o n {\displaystyle M_{\mathrm {Newton} }} and M S R {\displaystyle M_{\mathrm {SR} }} . If no time dilation exists, then those muons should decay in the upper regions of the atmosphere, however, as a consequence of time dilation they are present in considerable amount also ...
He is best known for conducting the Ives–Stilwell experiment, [15] which provided direct confirmation of special relativity's time dilation. Ives himself regarded his experiment as a proof of the existence of the ether and hence, as he suggested, a disproof of the theory of relativity. [15]

The difference that Ives and Stilwell measured corresponded, within experimental limits, to the effect predicted by special relativity. [ p 7 ] Various of the subsequent repetitions of the Ives and Stilwell experiment have adopted other strategies for measuring the mean of blueshifted and redshifted particle beam emissions.
