Abstract
The characteristics of the light scattered by microemulsions in the vicinity of a percolation threshold indicate the existence of strong and long range attractive forces between micelles. Hydrodynamic interactions are also present but show no evidence of long range character.

Résumé
Les caractéristiques de la lumière diffusée par des microémulsions au voisinage d'un seuil de percolation indiquent l'existence de forces attractives à longue portée entre micelles. Les interactions hydrodynamiques sont également présentes, mais n'ont pas de comportement à longue portée.
