Abstract
The dynamical structure factors of the liquid Ge are calculated theoretically and compared with the recent experimental results obtained by the inelastic X-ray scattering. The calculation is carried out by the simple purely theoretical method, i.e. by the viscoelastic theory, which is based on the effective pair potential obtained by the pseudopotential perturbation theory and the static structure factor calculated by the integral-equation theory in the modified hypernetted-chain (MHNC) approximation. It is shown that the calculated dynamical structure factors are in qualitative agreement with the experimental results and that the calculated dispersion relation agrees well with the experimental one.
