Namely hartree

In 1927, a year after the publication of the Schrödinger equation, Hartree formulated what are now known as the Hartree equations for atoms, using the concept of self-consistency that Lindsay had introduced in his study of many electron systems in the context of Bohr theory. Hartree assumed that the nucleus together with the electrons formed a spherically symmetric field. The charge distribution of each electron was the solution of the Schrödinger equation for an electron in a pot… WitrynaHartree-Fock equation which for a small two particle system lets us understand how well the Hartree-Fock method is. Our results focus on 1 dimension where we have, for example, found self ... namely electrons, protons, and neutrons. The approximation we will use for this is the Hartree-Fock method, for which the underlying assumption is …
