Abstract

We report measurements of the Lande g-factors for the 5d6s ³D₂ hyperfine levels of ¹⁷⁶Lu⁺ to a fractional inaccuracy of 5× 10^-7. Combining these measurements with theoretical calculations allows us to estimate hyperfine-mediated modifications to the quadrupole moments for each state and infer a value of δΘ= 1.59(34)× 10^-4 ea₀² for the residual quadrupole moment of the ¹S₀↔³D₂ hyperfine-averaged clock transition.
