  We propose an experimental protocol to directly observe the Kondo effect by
scattering ultracold atoms with spin-dependent interactions. We propose using
an optical Feshbach resonance to engineer Kondo-type spin-dependent
interactions in a system with ultracold $^6$Li and $^{87}$Rb gases. We
calculate the momentum transferred from the $^{87}$Rb gas to the $^6$Li gas in
a scattering experiment and show that it has a logarithmically enhanced
temperature dependence, characteristic of the Kondo effect and analogous to the
resistivity of alloys with magnetic impurities. Experimentally detecting this
enhancement will give a different perspective on the Kondo effect, and allow us
to explore a rich variety of problems such as the Kondo lattice problem and
heavy-fermion systems.
