We present experimental evidence that the intensity correlations of light scattered from a cold-atom cloud are sensitive to the presence of small amounts of radiation trapping in an atomic sample of density 6 × 108/cm3, with an optical depth (for a resonant light beam) of 0.4. This density and optical depth are approximately an order of magnitude less than the density and on-resonance optical depth at which effects of multiple scattering in cold-atom clouds have been previously observed [Phys. Rev. Lett. 64, 408 (1990)].

  12. The time scaling for the data in Fig. seems to agree with that of the one-dimensional theory in Ref. 7. However, this is fortuitous because of a typographical error—the time axis of Fig. 2 in Ref. should be multiplied by 4.
