Abstract

The fourth moments of current spectra have been calculated for liquid lead using the potential and the corresponding molecular dynamics g(r) obtained by Mitra (1977). These results and the memory function approach are used to calculate the viscosities and dynamical structure function. An estimate of the shear viscosity is found to be in good agreement with the experimental value. The results for the symmetrised dynamical structure function obtained from different models are compared among themselves and with experiment.
