โฆ Synopsis
THE RAM PERTURBATION THEORY AND THE HARb DUMBBELL FLUID Ivo NEZBEDA Wlhm R. SMITH The RAM perturbation theom is ekxluated in the use of the hard dumbbell fluid and compared with computer simuhtion rcsuIts. The zeroth-order theory lieIds good agreement nith the centres pair correhtion functiongooo(r) even up to Iage dumbbell sphere sep;lr;ttions. thus sirowing that the basic idea of the theory is sound. Some possible reasons for the failure of 3 rehted perturbation theory are discussed.
