Our measurements indicate a continuous formation of a thick wetting film at the free surface of the binary system driven by the first order transition in the bulk at the monotectic point. We show that the behavior observed is that of a complete wetting at a tetra point of solid-liquid-liquid-vapor coexistence.en0927-775720021-3515520Elsevier ScienceBismuthGalliumLiquid metalsSurfaceWettingX-ray reflectivityPhysikJournal Article10.1016/S0927-7757(02)00056-0Other
