published as Phys. Rev. Lett. 113, 120402 (2014) · In this version of the preprint we have swapped the assignment of the eg+ and eg- states to the spectroscopic signals, thus correcting a wrong attribution in the previous version. As a consequence, the scattering lengths of the two states have been inverted. Hovewer, the main results of the paper remain unchanged. 5 pages (paper) + 3 pages (Supplemental Material)

We report on the first direct observation of fast spin-exchange coherent oscillations between different long-lived electronic orbitals of ultracold 173Yb fermions. We measure, in a model-independent way, the strength of the exchange interaction driving this coherent process. This observation allows us to retrieve important information on the interorbital collisional properties of 173Yb atoms and paves the way to novel quantum simulations of paradigmatic models of two-orbital quantum magnetism.
