Méthode post-Hartree-Fock

In computational chemistry, post–Hartree–Fock (post–HF) methods are the set of methods developed to improve on the Hartree–Fock (HF), or self-consistent field (SCF), method. They add electron correlation which is a more accurate way of including the repulsions between electrons than in the Hartree–Fock method where repulsions are only averaged.
