The Hamiltonian operator for the helium atom contains two kinetic energy terms, two nuclear-clectron attraction terms, and an electron-electron repulsion term. An approximate solution, W-1s(1)1s(2), of the Schrödinger equation for the helium atom can be found if one neglects one of the nuclear-electron attractive terms the electron-electron repulsion terms one of the kinetic energy terms both the the nuclcar-electron attraction terms a) b) c) d)

Consider the He atom, and assume that the two electrons reside in the 2s orbital. The next two items refer to this situation. - Ignoring electron-electron repulsion, what is the electronic energy of the atom (in eV)? Write down the corresponding electronic wavefunction. - Use perturbation theory to account for electron-electron interaction and write down an expression for the electronic energy of this atom. No need to evaluate integrals, but specify coordinates, integration volume and limits of integration.

3. The predecessor to Hartree-Fock was the Hartree method, where the main difference is that the Hartree-Fock method includes an trial wavefunction by writing it as a Slater Determinant, while the Hartree method uses a simple product wavefunction that does not capture anti- symmetry. In particular, for a minimal-basis model of, the Hartree method's trial wavefunction is given in the while the Hartree-Fock trial wav is given by where and are molecular orbitals, and and coordinates of electron...
