| contents | The hyperfine structure of atoms and ions is widely used in fundamental and applied research. Accurate knowledge of hyperfine splitting values is essential for quantum metrology applications as well as for improving the performance of systems designed for quantum computing and simulation. We present refined values of the hyperfine splitting frequencies of the ground and clock states of thulium atom, $f_{g}^\textrm{HFS}=1\,496\,550\,658.23(3)$\,Hz and $f_{c}^\textrm{HFS}=2\,113\,946\,873.08(9)$\,Hz, respectively. The measurements are performed on an ultracold atomic ensemble in an optical lattice using combined microwave and optical transition spectroscopy. Our results improve the accuracy by 2 and 7 orders of magnitude for $f_{g}^\textrm{HFS}$ and $f_{c}^\textrm{HFS}$, respectively, compared to the previously published values. We also refine the value of the Landé g-factor of the clock level to $g_c = 0.85479(11)$. |
