Abstract
Using molecular dynamics, the intermediate scattering function has been calculated for liquid aluminium at about 985K for ten values of the wavevector k in the range 0.3-5.0 AA-1. Three pair potentials of the pseudopotential type have been tried. The corresponding dynamical structure factor for two of these potentials shows the existence of a collective excitation for k-1. The frequency of the excitation as a function of k follows a dispersion curve similar to that found earlier for rubidium by Rahman (1974).Keywords
