Structure factor and effective two-body potential for liquid gallium

The structure factor of gallium has been measured by neutron scattering at temperatures 326 and 959 K and densities 0.0525 and 0.0490 at./A${̊}^3$ (6.08 and 5.674 g/${\mathrm{cm}}^3$). The domain of measured wave vectors ranges from 0.26 to 16.2 A${̊}^{\mathrm{-}1}$. The precision of the experiments allowed us the determination of an effective pair potential between the gallium atoms at these two thermodynamic states.
