Theoretical calculations of the third virial coefficient for the pure components of all alkali metal vapours have been carried out using recently reported potential energy surfaces for the doublet and quartet states in which the interaction of three 2S ground-state atoms may evolve. The discrepancy

β¦ Synopsis
This note presents an efficient and fast method for evaluating the third virial coefficient for radially symmetric two-body potential functions. The computational method uses a list processing scheme based on a proper multidimensional integration formula and is considerably superior to the traditional methods based on product one dimensional formulas. The method of the present note has application to other areas of mathematical physics.

The second and the third virial coefficients in the lattice model of athermal mixtures of molecules of difierent sizes are calculated. Ail computations have been done for two-and three-dimensional simple square and simple cubic lattices.
A method is given for computing the fourth virial coefficient D(fl for a pairwise additive spherically symmetric interaction potential. Taking one of the four interacting particles as origin and using the appropriate co-ordinate transformations in the usual way the ninefold integrals defining D(fl a
