Abstract
To be able to derive all macroscopic properties of the condensed system, it is necessary to know the pairwise particles potential of the system. In order to study these properties, a molecular dynamic experiment has been performed on liquid copper, at 1393 K. For the above mentioned experiment the pair potential has been calculated by inverting the Week–Chandler–Anderson (WSA) perturbation theory. With this potential the velocity auto-correlation function φ(t), the pair correlation function g(r) and the transport quantities like self-diffusion coefficient D were calculated. The calculated data were compared to the experimental one and the agreement was rather good.
