`   Just found the note that you put on the requested articles page!  What exactly were you after for electron geometry?  The reason that I made a redirect was that a quick goggle search returned only molecular geometry results (at least in the first page).  I have seen plenty of derivations for the ``size`` of an electron (its wavelength or the spatial volume containing 99% of its wavefunction etc) but nothing I would call geometry.  Perhaps you could elaborate?  Sorry about the misunderstanding   `
