Abstract
The dynamical structure factors of the metallic glass Ca70Mg30 and the same sample after crystallisation have been determined for momentum transfers between 0.4 and 4 AA-1 and energy transfers h(cross) omega =E0-E between -40 and 6 meV using a thermal neutron time-of-flight spectrometer. The low-frequency modes reported in a recent experiment in a different metallic glass have been studied at room temperature with improved resolution. Their dependence on momentum transfer is discussed in detail.Keywords
