Popis: The counterpoise (CP) method to evaluate the SCF basis set superposition error (BSSE) is corrected for the He 2 van der Waals system with a method based on the polarization-function counterpoise (PCP) methodology. The equivalence between the over-estimation introduced when using the CP method and that portion of BSSE inherent in the exchange component is analyzed.
