In these experiments we employ laser-cooled single trapped ions. The optical frequencies are controlled by a frequency comb and I2 line locked laser system.

Our experiment is aimed at precisely testing the available atomic calculations and in particular atomic wave functions the knowledge of which is needed for interpreting a precise measurement of atomic parity violation in heavy alkaline earth atoms through light shifts in the narrow optical 6s2S1/2-5d2D3/2 single photon transition. The weak mixing angle can be determined precisely from the weak interaction contributions between primarily the nuclear neutrons and the atomic valence electron to the atomic binding.Indico - Integrated Digital Conference Powered by IndicoGSI Helmholtzzentrum f{\"u}r Schwerionenforschung GmbH | Planckstr. 1 | 64291 Darmstadt | Telefon: +49-6159-71- 0 | Impressum (in German) | Terms of Use",
