Abstract: identified!.The X-point maxima~an be considered as precursor effects of the low temperature Pa 3 phase.while the other diffuse scatterings may reveal the existence of competing phases.By comparing the observed intensity distiibution to that calculated using a microscopic mean-field theory (with the formalism of the symmetry adapted functions.up to the 1=12 terms) we evaluate different models of intermolecular potential.Van der Waals-type intermolecular interactions are found to account for the main features of the observed diffuse scatterim;:2.Elaborate models of intermolecular potential are being tested.~Below T 0 , the remaining X-ray diffuse scatteiing is analyzed to clarify the orientational order of the nearly degenerate configurations o(_the C6o molecules ("penta" and "hexa") which coexist in the Pa 3 phase.
