Abstract: A simple expression for the first coordination shell of the radial distribution function of the reference hard-sphere fluid is used in combination with Barker–Henderson perturbation theory to obtain the thermodynamic properties of triangular-well fluids. These properties are expressed analytically in terms of density, temperature, and range of the potential. It is found that the results are accurate for a wide range of densities and temperatures in comparison with existing simulation data.
