Query: Born-Oppenheimer potential energy surfaces for Kohn-Sham models in the
  local density approximation   We show that the Born-Oppenheimer potential energy surface in Kohn-Sham
theory behaves like the corresponding one in Thomas-Fermi theory up to
$o(R^{-7})$ for small nuclear separation $R$. We also prove that if a
minimizing configuration exists, then the minimal distance of nuclei is larger
than some constant which is independent of the nuclear charges.
