Web10.2 Self-consistent ﬁelds Iterative, self-consistent approaches similar to the Hartree-Fock method can be used to calculate properties of atoms, solids or molecules. All that changes is Vion. For non-central potentials appropriate boundary conditions are needed (e.g. periodic in the case of crystals). The origin of the Hartree–Fock method dates back to the end of the 1920s, soon after the discovery of the Schrödinger equation in 1926. Douglas Hartree's methods were guided by some earlier, semi-empirical methods of the early 1920s (by E. Fues, R. B. Lindsay, and himself) set in the old quantum theory of Bohr. In the Bohr model of the atom, the energy of a state with principal quantum number n is given in at…
