Abstract :
The understanding of the intermolecular pair potential is important for determining the physical and
chemical properties of the matter. The new data for noble gasses was calculated with Soft-Core
Double Yukawa Potential (SCDY). We studied the effect of the Soft- Core potential on the phase
behavior with Hartree-Fock-Dispersion (HFD) Potential. This model had a steep repulsion
exponential term and double Yukawa potential which represents correctly the radial dependence of
repulsive and long range energy respectively. The method was analyzed using sigma plot (SP-13)
software. In order to find a correlation between variables Spearman correlation coefficient was used.
Results showed that high content values for Ne-Ne, Ar-Ar, Kr-Kr, Xe-Xe of the pair potential which
were fitted with HFD-B Potential. This work was used the Yukawa potential and evaluation of it’s
the parameters to present potential. The results were accurate and in according to previous studies. In
conclusion, was summarized that potential was adjusted in two forms of (HFD and SCDY) potentials.
