摘要
A new an-electron Kohn-Sham method for molecules and clusters is introduced and applied. The local Kohn-Sham exchange potential and the exchange-energy are treated exactly. The method yields high quality one-particle spectra. An exchange-correlation charge density which generates the exchange-correlation potential is introduced. Tt may turn;out to beef great interpretative value. Within the new Kohn-Sham method the exchange part of this density is constructed.
