On a mesuré l'élargissement des raies de résonance Mössbauer dû à la diffusion atomique, dans le système V-57Co*, entre 1200°C et 1600°C, en utilisant une technique de détection des électrons de conversion. Par comparaison des résultats avec des données classiques de diffusion macroscopique, il apparaît qu'un mécanisme bilacunaire pourrait contribuer au transport de matière au-dessus de 1450°C.The diffusion broadening of the Mössbauer resonance was measured in a V-57Co* system over the temperature range 1200°C to 1600°C using an electron conversion technique. Comparing Mössbauer data with values of the macroscopic diffusion coefficient suggests the occurence of a divacancy mechanism for atomic transport above 1450°C
