Laser spectroscopy of 176Lu+
Abstract
We perform high resolution spectroscopy on 176Lu+ including the 1S03D1 and 1S03D2 clock transitions. Hyperfine structures and optical frequencies relative to the 1S0 ground state of four low lying excited states are given to a few tens of kHz resolution. This covers the most relevant transitions involved in clock operation with this isotope. Additionally, measurements of the 3D2 hyperfine structure may provide access to higher order nuclear moments, specifically the magnetic octupole and electric hexadecapole moments.
