✦ Synopsis

Vibrational densities of states g(E) and scattering functions S(Q, E) have been measured for amorphous silicon, amorphous germanium and Se,_,Ge, glasses. Computer simulations of g(E) and S( Q, E) not only show good agreement with experiment, hut also give the localization characteristics of the normal modes, revealing some novel low-frequency quasi-localized modes.
