• The mobility μ and the diffusion coefficient D of silver ions in Ag_2S, Ag_2Se and alloys Ag_2S_<1-z>Se_x have been measured by the aid of tracer technique using Ag^<110m>. The ratio μ/D is found to deviate from the Einstein relation remarkably. Although such deviation is usually attributed to the existence of correlation between successive jumps of a diffusing ion, the present substances are so much disordered that the correlation effect theory cannot be applied. Recently Yokota has proposed a new model appropriate to our substances. The experimental results are compared with his theory with a minor modification. It is proved that the theory is applicable to our substances.
