The approximation exactly reproduces the well-known results for D = 1 and D = 3, while for D = 2 it compares well to the numerical results for densities not very close to the freezing density.journal articlehttp://dx.doi.org/10.1080/00268979500101211http://www.tandfonline.com/metadata only access536FluidTermodinámica2213 Termodinámica
