One- and two-center physical space partitioning of the energy Salvador
... Hartree-Fock case to the fuzzy atom DFT energy decomposition did not give satisfactory results at all. In fact, one could anticipate that if one uses the same simple direct approaches in DFT which were successful in HF, then one may get difficulties: there is no obvious way to decompose the exchange ...

... simulated γ-ray annihilation spectra of a target, which depends on the electron wavefunctions, will be the same when using either HF or post-HF models, but will be different from those simulated using the DFT models. The choice of basis set is also important for the development of an accurate model. ...
