  We report our experimental results on the collisional physics between
non-S-state atoms (ytterbium (Yb), effectively a two-electron system, in the
metastable ${}^3\mathrm{P}_2$ state) and S-state atoms (lithium (Li), an alkali
metal, in the ground state). At low magnetic fields, by measuring inelastic
interspecies collisional losses in the double quantum degenerate mixture we
reveal the strong dependence of the inelastic losses on the internal spin
states of both species and suppressed losses in stretched state configurations.
Increasing the magnetic field up to 800 G we further investigate the magnetic
field dependence of the collisional interactions. There, smoothly increasing
inelastic losses are observed towards higher fields. The combined knowledge of
both the magnetic field and the spin state dependence of the collisional losses
of this prototypical mixture system of non-S-state and S-state atoms provides a
significant step forward towards controllable impurity physics realized in the
Yb-Li ultracold system.
