the deep BEC regime, the fraction Z is sensitive to the Fermi temperature TF. In particular, our data show Z∝ √TF at unitarity, in good agreement with theory. Further more, we have found a progressive departure of our measured Z value from theory as the system enters the BCS regime, calling for further investigation in both theory and experiment.
