Query: Photoassociation spectroscopy of ultracold $^{173}$Yb atoms near the
  intercombination line   We report on photoassociation (PA) spectroscopy of a degenerate Fermi gas of
$^{173}$Yb atoms near the dissociation limit of the spin-forbidden
${^1}S_0-{^3}P_1$ intercombination transition. An atom-loss spectrum is
measured from a trapped sample for a spectral range down to $-1$~GHz with
respect to the $f=5/2 \rightarrow f^\prime=7/2$ atomic resonance. The spectrum
shows eighty PA resonances, revealing the high nuclear spin nature of the
system. We investigate the Zeeman effect on the spectrum near a detuning of
$-0.8$~GHz, where we examine the quantum numbers of the Zeeman levels using
various two-component spin mixture samples. Finally, we measure the atom loss
rate under PA light for several pronounced PA resonances.
