Laser Spectroscopy of $^{176}\mathrm{Lu}^{+}$
POSTER
Abstract
Singly ionized lutetium $^{176}\mathrm{Lu}^+$ possesses low-lying metastable D levels where the corresponding decay channels have been proposed as promising optical clock transitions. Here we report laser spectroscopy of the $^3D_1$, $^3D_2$, $^3P_0$, and $^3P_1$ levels relative to the $^1S_0$ ground state. The hyperfine structure for each level, the allowed E1 transitions for detection and cooling, and clock transitions are all determined. These measurements provide a useful reference for establishing optical clock operation with this ion.
