By means of time-of-flight neutron inelastic scattering techniques we have obtained the generalized vibrational densities of states G(ω) of undoped polycrystalline and amorphous Fe40Zr60 and of amorphous samples doped with 1 and 7 at.% Kr. The amorphous compound displays a triangular shaped G(ω) which is very different from the strongly structured crystalline modification. Concerning the amorphous alloys, the energetic range of the additional Kr modes indicates that the Kr atoms are embedded in their host matrix as single atoms or perhaps small clusters and not as bubbles as was found in metals.
