 See the essay by S.-G. Wang and W.H.E. Schwarz "On Closed-Shell
 Interactions,
 Polar Covalences, d Shell Holes, and Direct Images of Orbitals: The Case of
 Cuprite", published in Angew. Chem. Intl. Ed. 2000, 39(10), pages
 1757-1762.
 They do analyse, in quite some detail, that is *actually* seen in this kind
 of experiments - and it is not a direct image of a single molecular orbital.
