Velocity distribution of Feshbach molecules. The angular integral (black points) of an average of 15 images with a time of flight of 15 ms (shown in the inset) was fitted with FermiDirac (blue line) and Gaussian (red line) distributions. Although the Gaussian fit overestimates the occupation at lower velocities, the data are well described by a FermiDirac distribution, which accounts for the Pauli blocking. The fit of the FermiDirac distribution results in T / T F = 0.28(1).
