An Electron Microscope for Viewing a Deformed Nucleus
Abstract
The metastable 2F7 / 2 state is predicted to be sensitive to the structure of the deformed ytterbium-173 nucleus in two ways. First, the high multiplicity of the electronic state (J = 7 / 2) allows the high spin (I = 5 / 2) nucleus to leave fingerprints of its multipole moments on the hyperfine structure, up to and including (at least in principle) the nuclear magnetic 32-pole moment. Using the fact that the F state is both long-lived and easily read out using techniques developed for quantum information processing, we are performing the first spectroscopy of this hyperfine structure. Second, the electric quadrupole hyperfine interaction in 173 Yb+ has been predicted to quench 4 of the 6 hyperfine levels of the 2F7 / 2 state from the 5-year lifetime of the other isotopes to the clock-friendly timescale of about 1 day. We will present prospects for achieving sub-Hz accuracy of the hyperfine splittings and lifetime measurements of the quenched hyperfine levels of 173 Yb+ and their implications for clockwork and electron microscopy of the shape of a nucleus.
