Abstract

The hyperfine transitions in the 399 nm $^1S_0\leftrightarrow ^1P_1$ line in $^{173}Yb$ overlap with the transition in $^{172}Yb$. We use transverse laser cooling on this line to selectively deflect $^{173}Yb$ atoms from a thermal beam containing both isotopes. We then use an acousto-optic modulator to span the frequency difference between the hyperfine transitions, and hence measure hyperfine structure in the $^1P_1$ state. Our precise values for the hyperfine constants, $A_{173}=57.693\pm 0.006 MHz$ and $B_{173}=609.028\pm 0.056 MHz$, improve previous values significantly.
