We present our experimental results (structure factors) obtained by neutron scattering on liquid Al-Ge alloys at 20, 40, 60, and 80 at.% aluminium at the temperature of 977 deg C. The alloy keeps, even at high aluminium concentrations (>60 at.% aluminium), a characteristic shape, which is more that of pure liquid germanium rather than the metallic one approximation from very simple interatomic potentials like hard sphere ones. We improve the interpretation by adding a Silbert-Young repulsive potential, with which we obtain a calculated total structure factor which agrees (within 2-5% following the composition and the q value) with our experimental total structure factor.
