The wave-number-dependent Lamb-M\"ossbauer factors (LMF's) of big and small particles in a glass of neutral hard spheres are investigated within mode-coupling theory by varying size ratio {δ}, total packing fraction {η}, and concentration c₁. It is possible to form a glass by the big particles only, while the small particles retain their mobility. Diffusion blocking of small particles is achieved by increasing either {η} or {δ}. The wave-number dependence of the small particles' LMF shows characteristic deviations from a Gaussian in contrast to big particles' LMF, which is almost Gaussian.
