Abstract
The energies of rays from the 10.27-MeV () transition in have been measured in an annular Ge (Li) detector at 0 and 180°. and capture reactions in a differentially pumped gas target were used to produce recoiling ions with two different very accurately known velocities. We observe a tranverse Doppler shift of 10.09 ± 0.41 keV for the capture reaction. This allows us to determine relativistic time-dilation effects at velocities of to an accuracy of 3.5%. Our results are in very good agreement with the prediction of special relativity.
