Figure 4: Quantitative analysis of a more elongated prolate configuration.
From: Atomic scale dynamics of ultrasmall germanium clusters
(a) Refined parametric model, peaked at the estimated atomic positions. Green and red dots correspond to 1 atom and 2 atoms, respectively. (b) Outcome of the ab initio calculation. It can be seen that a seven-membered ring is present. In addition, smaller fragments, consisting of 3–4 atoms are found to correspond well to the predicted ground states of trimers and tetramers.
