| Abstract: | The variational fluid perturbation theory is used to calculate the Hugoniot curves of liquid helium using the exponential six reference potential.An effective potential which incorporates many body effects is given by means of comparison of the theoretical and experimental data.This potential is fairly close to the optimum potential given by Nellis et al.Our study shows that when the shock compression properties for high temperature and high density fluid are calculated,interatomic many body effects are much more important and have the effect of softening the two body potential. |
