Three-body probability (solid gray curve in arbitrary units) as a function of the hyperradius and corresponding effective three-body potential (solid black curve), obtained from the separable model Eq. (15). For comparison, the Efimov potential (dotted curve) and the low-energy Faddeev three-body potential obtained from Eq. (7) for a Lennard-Jones potential with six -wave bound states (red dashed curve) are also represented. Note that for , the effective potential becomes strongly oscillatory (as can be seen from the nearly vertical lines) in order to reproduce the wave function. Since the physics in that region is correctly described by coupled potentials, the effective potential is not a meaningful construct in that region and the short-range oscillations have no particular significance.
