Phys. Rev. Lett. 83, 5266–5269 (1999)Coherent Backscattering of Light by Cold AtomsReceived 30 July 1999; published in the issue dated 20 December 1999 Light propagating in an optically thick sample experiences multiple scattering. It is now known that interferences alter this propagation, leading to an enhanced backscattering, a manifestation of weak localization of light in such diffuse samples. This phenomenon has been extensively studied with classical scatterers. In this Letter we report the first experimental evidence for coherent backscattering of light in a laser-cooled gas of rubidium atoms. © 1999 The American Physical Society URL:
