The laser-spectroscopic frequency measurement of Doppler-shifted optical lines in the forward and backward directions of a fast ion beam permits a sensitive test of the relativistic Doppler formula and, hence, the relativistic time-dilation factor gamma(SR) = 1/root 1-v(2)/c(2). An experiment on Li-7( ), stored at a velocity of v = 0.065c in the Heidelberg heavy-ion storage ring TSR, has confirmed time dilation with unprecedented accuracy limiting deviations to below 2.2 x 10(-7). Ongoing improvements on the experimental setup will further tighten this limit.
