Description
Atomic hyperfine structure provides a window into the structure of nuclei. High-precision atomic theory is essential for extracting model-independent nuclear observables from hyperfine measurements – permitting the interrogation of nuclear models. Such studies also allow the testing of atomic structure theory in the nuclear vicinity, which is needed for low-energy searches for new physics beyond the Standard Model.
I will present the results of a collaboration with atomic clock experimentalists at the German national metrology institute, Physikalisch-Technische Bundesanstalt (PTB), where unparalleled experimental precision, in conjunction with state-of-the-art atomic theory, allows the extraction of higher-order nuclear moments of Yb-173 for the first time.
