Optical detection of a BCS transition of lithium-6 in harmonic traps

We study the detection of a. BCS transition within a sample of lithium-6 at oms confined in a harmonic trap. Using the local density approximation we c alculate the pair correlation function in the normal and superfluid state a t zero temperature. We show that the softening of the Fermi hole associated with a BCS transition leads to an observable increase in the intensity of off-resonant light scattered from the atomic cloud at small angles.
