Abstract
Coherent backscattering is a multiple scattering interference effect which enhances the diffuse reflection off a disordered sample in the backward dir ection. Classically, the enhanced intensity is twice the average background under well chosen experimental conditions. We show how the quantum interna l structure of atomic scatterers leads to a significantly smaller enhanceme nt. Theoretical results for double scattering in the weak localization regi me are presented which confirm recent experimental observations.
