abstract:
Dispersion of collective modes in metallic glass (Zr40Be60, composed of disparate mass particles) was
measured at small-angle spectrometer BRISP at the ILL what enabled us to extend to lower momentum
transfers unlike to high-angle spectrometer IN4 at the ILL. It was shown that the behavior of the optical
mode in the metallic glass is similar to the behavior of optic modes in the other systems with non-sized
atoms(liquid LiPb, inert gas mixtures with high density (He65Ne35).
