    • Atomic correlation energy differences by means of a polarization potential 
      Fuentealba Rosas, Patricio; Stoll, Hermann; Savin, Andreas (1988)
      Correlation energy differences have been evaluated using an empirical polarization potential for the two-, three-, and four-electron atom series. In contrast to local-density approximations the Z dependency of the correlation ...
    • Electron affinities of alkaline-earth atoms by means of different density functionals 
      Fuentealba Rosas, Patricio; Savin, Andreas; Stoll, Hermann; Preuss, Heinzwerner (1989)
      Various correlation energy density functionals have been used to evaluate the electron affinities of the alkaline-earth atoms. A related approach based on polarization potentials was also tested. The results give evidence ...
