Einfaches Modell für monoatomare klassische Flüssigkeiten
A simple approximation for the conditional time-dependent pair distribution functionP(r′t ¦ rt) is proposed. With this approximation the van Hove-correlation-functionGd(rt) is computed and compared with Ludwig's1 computer results for liquid A1. Then we determine the velocity autocorrelationfunction ψ(t) under special assumptions for the particle motion. That function is compared with Rahman's2 computer results for liquid Ar.
