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 ...
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.
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 Ives–Stilwell experiment was carried out by Herbert Ives and G.R. Stilwell first in 1938 [22] and with better accuracy in 1941. [23] It was designed to test the transverse Doppler effect – the redshift of light from a moving source in a direction perpendicular to its velocity—which had been predicted by Einstein in 1905.
He is best known for the 1938 Ives–Stilwell experiment, which provided direct confirmation of special relativity's time dilation, [2] although Ives himself did not accept special relativity, and argued instead for an alternative interpretation of the experimental results. [3]

And in fact, that effect was measured in 1938 by Herbert E. Ives and G. R. Stilwell (Ives–Stilwell experiment). [102] And Lewis and Tolman (1909) described the reciprocity of time dilation by using two light clocks A and B, traveling with a certain relative velocity to each other. The clocks consist of two plane mirrors parallel to one ...
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.
