Abstract Recent measurements of the tracer coefficient of self‐diffusion in silver by Rothman, Peterson, and Robinson are analysed. In conjunction with the data on the equilibrium concentration of vacant sites by Simmons and Balluffi, with the temperature dependence of the isotope effect of self‐diffusion and with quenching experiments a consistent set of vacancy properties is deduced. In the usual notation the following mono‐ and divacancy properties are obtained: E 1v F= 0.99 eV, E 1v M= 0.84 eV, S 1v F= 0.5 k , v 1v M ≈4 × 10 13 s −1 , E 2v M− E 2v B= 0.34 eV, and Δ S 2v ≈ 2.6 k . These values are in good agreement with annealing experiments.
