Inelastic X-ray and neutron scattering experiments are powerful tools on studying atomic dynamics in a liquid. These are complemental technique for liquid dynamics due to their different characters. As an example of structurally disordered materials, we report the atomic dynamics on liquid Ge by means of the inelastic X-ray and neutron scattering experiments. The acoustic phonon dispersion and the quasielastic scattering spectrum due to the structural relaxations are discussed in association with the anomaly in the static structure.
