Abstract
In the present work, the attractive branch of the effective pair potential is predicted by using p-v-T data of the Joule-Thomson inversion curve. It i s concluded that all loci of the thermodynamic stales of the inversion curv e correspond to the attractive branch of the effective pair potential. It i s also predicted that the minimum of the effective pair potential well, r(m ), is less than that of the isolated pair potential, because the attraction term has a longer range than the repulsion term.
