Query: Feshbach resonances and molecule formation in ultracold mixtures of Rb
  and Yb($^3$P) atoms   We have investigated magnetically tunable Feshbach resonances in ultracold
collisions of Rb with Yb in its metastable $^3$P$_2$ and $^3$P$_0$ states,
using coupled-channel scattering and bound-state calculations. For the
$^3$P$_2$ state, we find sharp resonances when both atoms are in their lowest
Zeeman sublevels. However, these resonances are decayed by inelastic processes
that produce Yb atoms in $^3$P$_1$ and $^3$P$_0$ states. The molecules that
might be produced by magnetoassociation at the $^3$P$_2$ thresholds can decay
by similar pathways and would have lifetimes no more than a few microseconds.
For the $^3$P$_0$ state, by contrast, there are resonances that are promising
for magnetoassociation. There are resonances due to both rotating and
non-rotating molecular states that are significantly stronger than the
analogous resonances for Yb($^1$S). The ones due to rotating states are denser
in magnetic field; in contrast to Yb($^1$S), they exist even for bosonic
isotopes of Yb($^3$P$_0$).
