Which outcome arises when approximating a quantum system's many-electron wavefunction using Hartree-Fock method?

💡 Explanation

When approximating the many-electron wavefunction with the Hartree-Fock method, independent single-electron functions and average field approximation causes neglect of instantaneous electron-electron correlation. Therefore neglect of electron correlation effects results, rather than kinetic energy, nuclear repulsion inaccuracies or Pauli exclusion violations;those originating from different assumptions.
