title: Detection of BCS pairing in neutral fermi fluids via stokes scattering: the Hebel-Slichter effect.
abstract: We consider the effects of superfluidity on the light scattering properties of a two component gas of fermionic atoms, demonstrating that the scattered intensities of the Stokes and anti-Stokes lines exhibit a large maximum below the critical temperature when the gas is superfluid. This effect, the light scattering analog of the Hebel-Slichter effect in conventional superconductors, can be used to detect unambiguously the onset of pairing in an atomic gas in the BCS regime.
