Abstract:
Kihara has shown that the third virial coefficient of a Lennard-Jones 6—9 gas can be expressed as a convergent power series of the form Σj βj(s)θ(s—6)j/s with θ=ε/kT. In this paper the coefficients βj(s), which are rather complicated double integrals, are developed and applied to the case s=9. For j & lt;20 the coefficients are obtained by numerical quadrature, using high-speed computing equipment. Asymptotic formulas for arbitrary s are used to extrapolate the numerical results for s=9 into the range 20 & lt;j & lt;100. Values of the normalized third virial coefficient, C9(0)(θ) and its derivatives, computed from Kihara's series, are tabulated for the range 0 & lt;θ & lt;2. An asymptotic expression for C8(0)(θ) is used to extend the tables to higher values of θ.
