Abstract
The temperature dependence of the density correlation function at next-neighbourdistances has been investigated for the liquid metal lead. This correlation function is asensitive parameter for changes in the local environment and its Fourier transform wasmeasured in a coherent inelastic neutron scattering experiment. The zero-frequencyamplitude related to the long time decay of density fluctuations decreases in a nonlinearway and indicates a change in dynamics above the melting point. The derived generalizedlongitudinal viscosity shows a decrease near this temperature range. From theseobservations we suppose that solidification sets in on a microscopic level distinct above themelting point.
