摘要：

The isotope effect E = d In(D)/d In (1/root m) of Co diffusion in structurally relaxed Co86Zr14 and Co81Zr19 glasses has been measured by means of a radiotracer technique. Within experimental accuracy no isotope effect was detected (E < 0.04). This suggests a highly cooperative diffusion mechanism. The connection between diffusion and collective low-frequency relaxations in glasses is discussed.
