- The polarization so defined is not to be confused with a dipole moment. For the situations we consider here, the ground state of the cell has no dipole moment, although it may have a quadrupole moment. The cell polarization simply measures the degree to which the electronic charge is aligned and the direction of that alignment.

- Since electrons in different cells are physically distinguishable (there being no wave-function overlap), the exchange coupling between them is zero. The Hartree and Hartree-Fock approximations are therefore equivalent in this case.

- For the standard cell, we take [formula omitted] to be the Coulomb energy of two electrons separated by one-third the dot diameter D, a physically reasonable first approximation. Varying [formula omitted]is roughly equivalent to changing D.
