Figure 4: AIM analysis of HeN@C60 at the MP2 level.
From: X-ray observation of a helium atom and placing a nitrogen atom inside He@C60 and He@C70
(a) Molecular depiction with displaying BCPs in red. (b) Cross-section contour map of electron density with bond paths in brown and BCPs in red. The contours [ea0–3] are at 2 l (l=±8, ±7,..., 0), and 0.0047 (heavy line).
