Abstract With the aid of Howard's theory for computing the correlation factor for self‐diffusion by divacancies, the influence of divacancies on the isotope effect for self‐diffusion in f.c.c. metals is calculated. It turns out that a divacancy contribution lowers the isotope effect. This result is compared with experimental values for palladium and silver, and with the usual interpretation of small isotope effects following Vineyard's theory.
