ON THE THEORY OF CLASSICAL FLUIDS
It is shown that the summation of a large class of diagrams in a development of the''cluster'' type allows establishment of an integral equation for the correlation function in classical fluids. According to one approximation, this equation reduces to that of Born, Green, and Kirkwood, and it reproduces more exactly than that of the virial coefficients. The more and more complicated corrective terms which render the equation exact are given. The three-body correlation function is calculated which, introduced in the equation of Yvon-Born-Green, allows calculation of the two-body correlation function. Thus the direct calculation of this function is confirmed, and it is shown that the integral equation includes corrections for the superposition approximation. (T.R.H.)
