I think there are some problems with the electron density of "neutral
spherical unperturbed atoms". For instance, for carbon atom,
spherical electron density can be only obtained using state-averaged
approaches like state-averaged MCSCF. One needs to average over all
components of the degenerate irreducible representation corresponding
to the ground state of carbon atom in p2 configuration.
At the same time, real molecules are computed using different
computational approaches so there is an inconsistency here.
Kind regards,

The deformation density is the difference between the total electron density of a molecule (calculated or experimental) and the electron density of "neutral spherical unperturbed atoms" superimposed at the same nuclear positions.
