摘要：

The fourth moments of current spectra have been calculated for liquid aluminium using the Duesbery-Taylor potential and corresponding Monte Carlo g(r) obtained by Michler et al. These results and continued fraction representation of the generalised correlation function are used to calculate the spectral function of the longitudinal current. The expansion is carried one step further than usual and the results obtained using different approximation for the memory function are compared with each other and with the molecular dynamics data based on the same Duesbery-Taylor potential.
