Journal ArticleDOI
Unitary transformations and pair energies
TL;DR: In this article, it was shown that the sum of the pair correlation energies depends on the choice of SCF orbitals, i.e., the energy improvement in a variational calculation using excitations of only one pair of orbitals.
Journal ArticleDOI
Koopmans’s theorem in the restricted open-shell Hartree–Fock method. II. The second canonical set for orbitals and orbital energies
TL;DR: In this paper, a generalization of Koopmans theorem in the restricted open-shell Hartree-Fock (ROHF) method is presented. But the results are restricted to the case where the state of an ion cannot be described by a single determinant.
Journal ArticleDOI
The correlation potential for two‐electron atomic ions
TL;DR: In this paper, the correlation potential for two electron atomic ions with atomic numbers from 1 to 10 using the charge density reconstructed from a natural orbital expansion of a Kinoshita-like atomic wave function was computed.
Journal ArticleDOI
Electron momentum spectroscopy of H 2 and D 2 : Ionization to ground and excited final states
TL;DR: In this paper, the authors measured the symmetric noncoplanar (e,2e) cross sections (momentum profiles) of H{sub 2} and D{ sub 2} for the transitions to the 2p{sigma}{sub u} and 2s{ sigma} excited ion states, relative to the ground-state ion transition, using a high-sensitivity multichannel momentum-dispersive electron momentum spectrometer (EMS) at an impact energy of 1200 eV.
Journal ArticleDOI
Bonding in FHF−, (HF)2, and FHF
TL;DR: In this paper, the authors compared the molecular orbital and electrostatic bonding viewpoint in FHF−, (HF)2, and FHF is compared from the perspective of molecular orbital bonding.
