Abstract
For liquid rubidium at 319°K moleculardynamics calculations using a realistic pair potential and a model system of 432 atoms have been performed. The cut-off radius for the potential was taken alternatively at 4.5 and 9.8 Å. The corresponding velocity autocorrelation functions and fourth moments of the scattering law were determined. The differences in the results for the two cut-off radii are attributed to long-range effects.
