STATISTICAL-MECHANICS OF RIGID PARTICLES - GENERAL ZERO-SEPARATION THEOREM

Modified distribution functions are defined by F*n(r 1,⋯,rn) = Fn(r1,⋯, rn) · exp[Un(r1,⋯,r n)/kT], where Fn(r1,⋯,rn) is the distribution function and Un(r1,⋯,rn) is the mutual potential energy for a set of n molecules. These modified functions are equivalent to those of empty domains (cavities) and are used to derive several general zero-separation relations for rigid particle fluids. © 1979 American Institute of Physics.
