| Zusammenfassung | We report on the first coherent excitation of the highly forbidden 2S1/2 →2F7/2 electric octupole (E3) transition in a single trapped 172Yb+ ion, an isotope without nuclear spin. Using the transition in 171Yb+ as a reference, we determine the transition frequency to be 642 116 784 950 887:6(2:4) Hz. We map out the magnetic field environment using the forbidden 2S1/2→2 D5/2 electric quadrupole (E2) transition and determine its frequency to be 729 476 867 027 206:8(4:4) Hz. Our results are a factor of 1x105 (3x105) more accurate for the E2 (E3) transition compared to previous measurements. The results open up the way to search for new physics via precise isotope shift measurements and improved tests of local Lorentz invariance using the metastable 2F7/2 state of Yb+. |
