Abstract: | Laser spectroscopy at the heavy ion storage ring TSR in Heidelberg allows for precision experiments testing the limits of the special theory of relativity. With an optical -type three-level system of7Li+ the Doppler shift has been measured by saturation spectroscopy as a test of the time dilatation factor = (1 –
2)–1/2 at an ion velocity of = 6.4% c. A precision of![Delta](/content/jm64190207870541/xxlarge916.gif) / < 9 × 10–9 has been obtained, which sets a second-order limit of 1.1 × 10–6 for any deviation from the time dilatation factor. The fourth-order limit of this deviation is set below 2.7 × 10–4 by the present experiment. These limits are given at a 1 confidence level. |
