with the wave function, can be especially advantageous for a joint treatment of
X-ray and polarized neutron data [ 72 ]. The databank of theoretical pseudoatoms
can open new perspectives for routine X-ray charge density analyses, especially of
larger molecular systems, provided technical advancements further improve data
quality.
