Figure 3: Density distributions.
From: Imaging the structure of the trimer systems 4He3 and 3He4He2
(a) Density distribution of He atoms in a random cloud projected into the x– y plane. (b–d) Density distributions of the third particle in the case where the first two are fixed at the positions of the red dots. The random cloud model (b) yields, with an exception of the areas very close to the first and second particle, a distribnution that is very similar to the experimetal one (c) and to the one of the QMC calculations (d). The grey cross marks the position of the third particle for the case of a hypothetical equilateral triangle.
