MATHEMATICAL COMMENT ON ADHESIVE HARD-SPHERE MODELS FOR FLUIDS

A mathematical discussion is provided on the relationship between Baxt er's adhesive hard sphere fluid and the hard sphere Yukawa fluid with sufficiently strong and short range attractive Yukawa tails. It is pro ved that the Percus-Yevick approximate solution of the Ornstein-Zernik e equation for the former fluid can be included mathematically in the generalized mean-spherical approximation solution with the Yukawa clos ure, and the equivalence conditions of both solutions are presented.
