Abstract 



The present authors have given an exact theory of the exchangecorrelation potential Vxc(r) in terms of (i) the exact groundstate electron density n(r) and (ii) the idempotent Dirac density matrix gamma(r,r') generated by the DFT onebody potential V(r), having n(r) as its diagonal element. Here, we display two approximate consequences: (a) a form of Vxc(r) generated by the semiempirically finetuned HF density of Cordero et al. (N.A. Cordero, N.H. March, and J.A. Alonso, Phys. Rev. A 75, 052502 (2007)) and (b) the exchangeonly potential Vx(r) determined solely by the HF ground state density for the Be atom.
