The static structure factor of liquid Li

We have used the classical Molecular Dynamics method to calculate the structure factor S( Q) of liquid Li and we compare this quantity with that measured by neutron scattering. We have employed a system of 1458 Li atoms interacting, via periodic boundary conditions, with a recently derived interionic pair potential. The good agreement between the calculation and experiment is taken to indicate that the explicit many body interionic forces are not important in liquid Li.
